In this post, I analyze the Stanford GSB MBA (also MBA and MSX) essays and additional information/resume/employment history/activities for Class of 2026 . My analysis of Stanford GSB interviews can be found here. For an overall quick analysis on M7 schools essays see here for an earlier post.
You can find results and/or testimonials from my clients admitted to the Stanford Classes of 2024, 2023, 2022, 2021, 2020, 2019, 2018, 2016, 2015, 2014, 2013, 2012, 2011, and 2010 here. My clients admitted to Stanford GSB have come from China, Europe, India, Japan, Mexico, Singapore, South Korea, and the United States and have had extremely diverse professional and educational backgrounds. The advice I provide below is based on that experience.
The essay questions for the Class of 2026 remain unchanged. While I have yet to see the application form (not open yet), I will bet it is unchanged as well. This blog is minor update from last year's. I know my advice is good given the number of my clients who get admitted and/or invited for GSB interviews.
Applicants can apply to both the MBA and MSX at the the same time. For candidates that fit the MSX work requirements of 8 years minimum by July 2018, this is a good option. My advice would be to explain in a couple of sentences in The Why Stanford essay why both options would be ones that you would consider. Regarding MSX, if you are interested in attending that program, I highly recommend getting in direct contact with the admissions office for that program. They are likely to provide you with much more personalized feedback on whether you are good applicant for the program.
Essay Questions
Essay A: What matters most to you, and why?
For this essay, we would like you to reflect deeply and write from the heart. Once you’ve identified what matters most to you, help us understand why. You might consider, for example, what makes this so important to you? What people, insights, or experiences have shaped your perspectives?
Essay B: Why Stanford?
Describe your aspirations and how your Stanford GSB experience will help you realize them. If you are applying to both the MBA and MSx programs, use Essay B to address your interest in both programs.
Length
Both essays combined may not exceed 1,050 words. We recommend up to 650 words for Essay A and up to 400 words for Essay B. We often find effective essays that are written in fewer words.

Optional Short-Answer Questions
Optional Question 1
Think about times you’ve created a positive impact, whether in professional, extracurricular, academic, or other settings. What was your impact? What made it significant to you or to others?
In the Essays section of the application, we ask you to tell us about who you are and how you think Stanford will help you achieve your aspirations. We are also interested in learning about the things you have done that are most meaningful to you. If you would like to go beyond your resume to discuss some of your contributions more fully, you are welcome to share up to three examples. (Up to 1,200 characters, or approximately 200 words, for each example)
Optional Question 2 (NOTE CANNOT CONFIRM THAT THIS QUESTION WILL USED THIS YEAR UNTIL THE APPLICATION IS OPEN)
Tell us about a time within the last three years when your background influenced your participation at work or school.
We know that each person is more than a list of facts or pre-defined categories. We are interested in how your background may have influenced your life experiences. In answering this question, consider how your background, such as your work, education, skills, interests, culture, socioeconomic status, sexual orientation, gender identity, race, ethnicity, where/how you grew up, and/or other factors, had an impact on your recent actions and choices. How did one specific aspect of your background influence whether or how you participated in a situation, interaction, or project? (Up to 1,100 characters, or approximately 180 words)
INTELLECTUAL VITALITY
The simple reality is that Stanford is for really smart people and specifically for people who want to think and explore: This is a school fueled and surrounded by innovation and collaboration. If you have ideas, there is no better place than Stanford GSB to explore them.
My clients who get interviews and most certainly those who are admitted are, without exception, objectively smart people. One primary way, but not the only way, to measure these criteria is by looking at the key numbers. For the Class of 2024, the GSB site provides the following:
GMAT Average (67% of admits): 737.
GRE Average (33% of admits): 163 (Verbal) and 164 (Quantitative)
GPA Average: 3.76
TOEFL: 113
These numbers reflect the fact that Stanford is the most difficult MBA program to get admitted to. When I am talking with a client or potential client, if I have somebody with a really strong academic background and I see a real sense of purpose and focus to their academic and professional career, I might advise them to apply to Stanford. And in the last few years, I have literally convinced three of my clients to apply to Stanford because basically I said, "Hey, you’re perfect, you’re what they are looking for." And that’s a sense. It’s not objective. And so, it’s just based on my experience. I am not always right about this, but I am right about it enough of the time to think I know when I have an applicant who is right for Stanford. There are also times, where I have the opposite conversation. If your academic performance at university (both in and out of the classroom) was not outstanding, Stanford will be extremely challenging to enter. I have had clients get in with GMAT and GRE scores that were significantly below average and GPAs that were not excellent but they were truly outstanding candidates. For example, I had a client admitted whose academic performance was solid but not excellent but whose leadership and impact at university was exceptional. This client's personal story and professional impact were also exceptional. The client also had the advantage of coming from a country and a region that has few MBA applicants.
DEMONSTRATED LEADERSHIP: THE CENTRAL ROLE OF LEADERSHIP AT STANFORD
Stanford should, like HBS, be associated with a leadership-focused education, which is reflected in its mission statement:
The three new impact essays that were added for 2019-2020 (Class of 2022) are certainly the ideal place to highlight your leadership potential. But beyond that, what you write in the two essays, resume, and application form should also take your leadership potential into account. It is also important to advise your recommenders on the importance of discussing your leadership potential.
PERSONAL QUALITIES AND CONTRIBUTIONS
I think reading what Stanford says about Personal Qualities and Contributions is the best place to start when thinking about this third criteria. In essence, Stanford wants to know why should be a part of the 6.2% of the applicant pool that they will be admitting. What makes you stand out? How will you contribute? What is it about your experience and attitude that will not only make you a good fit for Stanford but will give you the potential to make an impact to the Stanford community? This does not just come out in one particular place, but is something that will come out of your entire application as well as in an interview.
STANFORD IS LOOKING FOR HONESTY
In my analysis of Essay 1, I will discuss the critical importance of providing honest answers to Stanford's questions. I think that what has always made a winning set of essays for Stanford is the ability to commit to making an honest and insightful presentation of yourself. Based on my experience I can say the following are not effective:
1. Over-marketing: While I believe in the value of the marketing metaphor to some degree, I also believe you have to be able to understand that a crude, over-determined approach to doing so will not work here (For more about this, click here). If you are not real, assume a good reader will figure out that you are not. As mentioned above, I think Dean Moss is someone ideal for determining whether you are telling the truth or slinging bullshit.
2. Not writing your own essays. If your essays are not written in your own voice and don't reflect your English ability, don't expect to make it past Stanford's team. My own approach to helping my clients does not involve me writing their essays but instead I act as a coach, a close reader, and someone who can benchmark their work against those who have been admitted. I make the assumption that overly cooked essays that look like they were written by a professional journalist when you are not one or by a native English speaker when you are not one or similar inconsistencies are unlikely to succeed.
IS STANFORD RIGHT FOR YOU?
Stanford really does provide great advice about both the Stanford GSB essays and about how to handle your applications. Just start exploring their website! Also, see my discussion of Stanford GSB in my analysis of Essay 2. Don't make assumptions about what Stanford GSB is or based on what someone told you it is. Instead, make that determination yourself after sufficient research. If you are thinking about Stanford GSB and have not yet attended one of their Admissions Events, I suggest doing so if you can. Visiting when school is in session is ideal though likely to be impossible for at least Academic Year 2020-2021 because of Coronavirus. Most importantly try to talk to current students or recent alumni. In the present environment all schools are making great attempts to have a variety of online ways of learning about the school and connecting with students.
THE ESSAYS
SHOULD I WRITE ESSAY A OR B FIRST?
Applicants often ask me this question. I think it is important that knowing why you want an MBA, Essay B, be clearly established first. Therefore, at least at the conceptual level, you should have a clear answer to Essay B initially. You might do the writing in either order, but as I will discuss below, what matters to you most, Essay A, must be consistent with and complimentary to your rationale for pursuing an MBA. Stanford does not specifically ask you to write about your post-MBA goals in Essay B, but I would argue that it is impossible to explain why you need an MBA without explaining what you need an MBA for. And a major part of what you need an MBA for is what you will do after you finish at Stanford. Now it is possible that what matters most to you might actually relate directly to your goals, so the amount of detail about your goals need not be extensive in Essay B, but explaining why need you an MBA is at the core of this essay set.
Essay A: What matters most to you, and why?
This is the classic Stanford GSB essay question. If you want to enter into the MBA Class of 2026, you will need to find your answer to it.
WHERE DO SUCCESSFUL ANSWERS TO ESSAY A COME FROM?
In my experience, answers to this question that result in acceptance come from the HEART and the HEAD. The two combined will allow you to tell your story about what matters most. I suggest beginning with no fixed assumptions about what Stanford wants here. One of the easiest ways to write a bad version of Essay 1 is to have a theme that does not directly relate to your actual experience: Round pegs do not fit into square holes.
Stanford admissions states that there is no one right answer. Some applicants become paralyzed because they want THE RIGHT MESSAGE. You need to fully account for who you are and what you have done, but should not try to overly sell yourself to Stanford because that is simply at odds with the way in which the school selects candidates. Therefore don't focus on finding THE RIGHT MESSAGE, instead, be honest and give an answer that is real. If you are having some more fundamental difficulties with this question, one book I suggest taking a look at is Victor Frankl's Man's Search for Meaning. This classic is worth a look for anyone who is thinking about what their life is about. Frankl makes us think about meaning from the most extreme of perspectives, inside a concentration camp, and in the process helps us to understand that meaning itself is deeply tied to our own survival. If you need to engage in some self-reflection, Frankl’s book is one place to start. I might also suggest reading Plato or doing some meditation, but in my experience those take more time and Frankl's book has the advantage of being short, inexpensive, available at many libraries, and has been translated from the original German into at least twenty-two languages.
The answer may be real, but is it a good one? If you are not sure, look critically at Stanford GSB's mission statement discussed above in this post. Does what matters most to you fit within this mission to develop innovative, principled, and insightful leaders who change the world? Think about this statement in the widest possible way. Given the small class size and the highly collaborative nature of the program, admissions will only be doing its job right if they select students who fit into Stanford GSB's mission. Stanford is looking for leaders, but leaders come in many forms and the values and ideals that inform them vary greatly. In my experience, Stanford highly values "Thought Leaders" as well as those who demonstrate more standard forms of leadership. If what matters most to you is something that admissions can clearly connect to informing your ideals as a leader and your professional goals then you are on the way to forming an effective answer to what is Stanford's most unique essay question.
Some Common Types of What Matters Essays
While I am not known for giving examples or sample answers, I would like to discuss three common types of answers.
Abstract and metaphorical: Abstract and metaphorical answers can produce very creative responses. An example (Note all examples I will use here are not from my clients) would be "What matters most to me are the doors in my life." Using the whole concept of entering and exiting, this essay concept might work very well, but could easily generate a series of disconnected stories that don't leave the reader with a really clear answer. I have had clients use such answers effectively, but more often than not, the more abstract the answer, the harder it is to make into something really convincing. Remember that writing MBA essays is not primarily a literary exercise, so be careful with this approach.
Core value: A core value response might involve a very simple answer to the question, such as "What matters to me most is love." Applicants frequently stress out about giving simple answers to the question because they worry that the answer will be too common. I think it is a mistake to worry that your core conceptual answer is too common because you should assume that Stanford admissions has seen almost every possible answer to this question already. What is ultimately important is not the what, but the why and how you explain that why in the essay. Simple can work exceptionally well if it is a way to connect key aspects of yourself effectively. I have had a number of clients who were admitted with one to three-word answers to the question.
The Mission: A mission version of the answer works exceptionally well if your stated mission is really backed-up by your resume and other aspects of your application. An example would be "What matters most to me is protecting the Earth's environment for future generations." I have seen many answers like this that were truly excellent and resulted in admission for candidates who could really prove they had the mission in the past and would be continuing it in the future. On the other hand, I have seen so many bad answers that lacked believability because the applicant's biographical details did not align with the answer, and/or lacked a clearly stated mission with a scope that was clarified in Essay B.
While I have seen all three types result in admission, I have seen more Core Value and The Mission type answers work successfully.
Make a choice! All successful versions of this essay that I have read involve making a choice. That is to say, you must actually clearly indicate something that matters most. As someone who is frequently contacted by those who have failed to obtain admission to Stanford and want to know why, I often find that they don't make this choice. Their "what matters most" lacks clarity and unity. Make a clear choice and really explore it. This will best reveal your self-awareness and your passion.
Leverage the optional impact essays: The impact essays give you a place to tell detailed stories of leadership, teamwork, and accomplishment, so don't focus on such stories in Essay 1. Instead of focus on explaining yourself and what you most value. Let the impact essays show how you live out what matters most to you.
Finally, the map is not the territory: You are more than whatever you write in an essay. This is essay is just a slice of who you are. It is not everything, so don't expect you will have that one theme that explains everything you care about. You have to make a choice of topics here, but this is ultimately not an existential choice, it is a marketing choice. You are deciding what core message(s) about yourself will ultimately best give you a chance of admission to Stanford. The question itself is ultimately absurd for most people as what matters to them is one more than one thing. We have competing commitments: Often more than one thing matters most to us so we are constantly reprioritizing. We are complex and contradictory. Our beliefs and actions are not always in alignment. We worry about our choices. We have inner struggles. All of this is true and yet ultimately in terms of this essay you have to provide a clear answer to the question. Getting at what matters most is often determined by struggling with competing commitments and ultimately stating what is rhetorically most defendable and strategically most appealing.
Your objective in the essay is to demonstrate why you would greatly benefit from a Stanford MBA education. Stanford is proud of what they are and what they can offer. They can reject anyone and they do reject a higher percentage of applicants than other schools. One thing I think that separates great versions of Essay B (the ones that get applicants an interview) and mediocre versions (the ones that usually don't get applicants an interview) is the extent to which the applicant is able to show that Stanford is not a mere afterthought or an option, but actually a necessity to accomplish one's aspirations. Fully account for that in your essay. Learn as much as you can about Stanford and think deeply about who it will impact you.
2. Shows connectivity with Essay A. Whether the connection is extremely direct or relatively abstract, the reader should feel a sense of synergy between these essays. For those who have a mission (see above) type answers in Essay A, Essay B is an opportunity to explain how an MBA will help you carry out that mission. For those with other types of Essay A answers, the connectivity will be more indirect, but should still be intuitively obvious to the reader.
THIS IS A FUTURE DIRECTED QUESTION
Unlike some other "Why MBA" questions, Stanford is not asking about the past. You have Essay A, your resume, and the application form to discuss the past. This essay is about who you want to become. While Stanford does not require you to elaborate on your short and long term goals in this essay, without some consideration to your post-MBA future, it will not be very easy to write an effective answer to this question. You need not have an elaborate plan here. You hardly have the space for it. Instead of focusing on your goals, focus on your personal mission:
-How will you make a difference and how can Stanford help you do that?
-What impact do you want to make on the world that an MBA will help facilitate?
-What do you need to learn at Stanford in order to transform yourself for your future?
You need to be ambitious. Simply stating what your goals are and why Stanford is the best place for you to accomplish them is not exactly what you need here. Instead, you need to articulate a rationale related to why you want an MBA that is connected to Stanford's mission to train global leaders. For more about being ambitious and visionary, see here. While the Stanford essay may not require goals, you will need them if you are interviewed by an alumnus. Most Stanford interviews involve a discussion of goals. So having a well thought out set of goals, even if they are not written about extensively in Essay B is something that you should have in place. While many applicants will be able to successfully apply with relatively standard goals ("I want to be a consultant because..."), communicating aspirations requires going beyond the typical.
When formulating goals, the necessary prerequisite for formulating aspirations, I suggest going through a formal process of goals analysis. If you are still trying to figure out what you want to do with your life, you can use the following grid.
The following image may not work for all browsers. If so, see here. Click to enlarge it.
Step 1. Begin by analyzing your "Present Career." What roles and responsibilities have you had in clubs, part-time jobs, internships, volunteer activities, etc.? What was/is your functional role(s)? What was/are your responsibilities?
The Essay B writing process
After going through a process of reflection and analysis, prepare versions of Essay B that includes everything you want to say. Next, begin the process of revision. Here are a few key things to consider when revising:
1. Think about the most important thing you need admissions to know about what you want to do after your MBA and why Stanford MBA (or MBA/MSX) is the best place for you to do that. Begin your essay with that. Chances are good that on your initial draft the most important thing is somewhere in the middle or end of your essay.
2. Prioritize the rest of your content: What do they really need to know? Chances are you have lots of details that can be cut.
3. Make a formal argument: Your essay should be neither a set of disembodied points or a summary, instead, it should be a formal statement. Effective forms of this statement vary. The important part is that the reader should be able to understand it clearly and be convinced by it.
Once you have put together Essay B, consider how the rest of your application supports what you say in it. Without over-marketing yourself or even necessarily writing it directly in the essays, make that your other essays and other aspects of your application show how your potential will contribute to your future aspirations.
SURE IT IS AN "OPTIONAL ESSAY" BUT ONLY AN IDIOT WOULD NOT ANSWER IT!
Optional Question 1
Think about times you’ve created a positive impact, whether in professional, extracurricular, academic, or other settings. What was your impact? What made it significant to you or to others?
In the Essays section of the application, we ask you to tell us about who you are and how you think Stanford will help you achieve your aspirations. We are also interested in learning about the things you have done that are most meaningful to you. If you would like to go beyond your resume to discuss some of your contributions more fully, you are welcome to share up to three examples. (Up to 1,200 characters, or approximately 200 words, for each example)
. All the clients that I worked with who were admitted and/or interviewed by Stanford for the Classes of 2022, 2023, 2024, and 2025 wrote the impact essays. You should too!
Calling this an optional essay is just a confusing message to send to applicants because (1) it is not like a typical optional essay related to critical information or problems that have not been accounted for, which is the common topic for optional essays (Stanford has it, it is called Additional Information and is discussed below) and (2) anyone can and should answer this question! If you cannot identify 1-3 specific ways you have had impact in ANY SETTING (professional, extracurricular, academic, or other setting = ANY) that you have not covered elsewhere in detail in application (including the essay in the application, see below), there is a problem. I don't recommend writing about something you are covering in detail elsewhere in the required essays or application form but, of course, some overlap is likely (especially with respect to the application form content). Given that Stanford is looking for people who will have high impact throughout their careers, the essay is a great way to showcase your potential to be a high impact leader in the future. it is also an opportunity to show how you will add value at GSB. It is also a great chance to elaborate on a story that you could not include or fully discuss in your required essays.
Effective answers to this question will clearly state the activity engaged in, identify the impact, and explain why it was significant (made a difference) to your yourself or others. This chart will help you brainstorm impact essays:
Essay Outline | What was your role? | What does it mean? | Why will this essay sell them on you? |
Situation: When? Where? Who? What? How? | Effective answers to when, where, who, what, and how should all relate directly to your role in the situation. You are the hero or heroine of your story. | Your reader should have a clear understanding of the situation. They are not reading a mystery story, a poem, or some other form of writing where withholding information will be valued. | The situation needs to be one that the reader will believe, consider to be important, and hopefully be impressed by. |
Action Steps: What actions did you take?Action Step 1: Action Step 2: Action Step 3: | Stories break down into steps. For each step, make sure you are clear about what you did. | Each action step should be meaningful and demonstrate your potential. This is the core of the story and it is important the rationale for your actions be stated as clearly as possible. Effective essays involve both description and interpretation. | If you are actions are clear and their value is clear in terms of your leadership, analytical, engaged community citizenship, or unique background, you will be on a firm basis for selling your story to admissions. |
Result | Results should be stated as clearly as possible. Your relationship to the results should be clear. | Explain the significance of results clearly. | Make your results meaningful so that they will be impressive. |
I would suggest writing these short essays after determining the content for your required A & B essays as well as completing the application form, so you can see what has not been fully accounted for in your background that you really want Stanford to know. Aligning the content of impact essays to connect to theme of Essay A and/or to show your potential to accomplish your goals as mentioned in Essay B is something that I consider critical for making a great essay set.
Optional Question 2
(NOTE CANNOT CONFIRM THAT THIS QUESTION WILL USED THIS YEAR UNTIL THE APPLICATION IS OPEN)
Tell us about a time within the last three years when your background influenced your participation at work or school.
We know that each person is more than a list of facts or pre-defined categories. We are interested in how your background may have influenced your life experiences. In answering this question, consider how your background, such as your work, education, skills, interests, culture, socioeconomic status, sexual orientation, gender identity, race, ethnicity, where/how you grew up, and/or other factors, had an impact on your recent actions and choices. How did one specific aspect of your background influence whether or how you participated in a situation, interaction, or project? (Up to 1,100 characters, or approximately 180 words)
Give them a new perspective on you!
This is a behavioral question (See my MIT interview post for a full discussion of behavioral questions). I like this kind of question because it asks an applicant to apply something from their background to something they have done recently. Stanford gives the following advice for this question: "We know that each person is more than a list of facts or pre-defined categories. We would like an example of how one factor in your background has had an impact on your life." Please don't tell a story that overlaps with the content presented elsewhere in your application and especially not with your essay content. The point of Stanford's analysis of this question is just the opposite: Tell us about something else in your background and how it has impacted what you have done in some recent situation. For those who have been out of school for more than two years make it work related. For those still in school or who graduated within the last two years, you can make it work related or school related, whichever suits you. Stanford has seemingly excluded extracurricular activities for the very reason that work and school are more high stakes since what you do at school or work is more likely to directly impact you. That thing in your background could be a value, a lesson you learned, an activity or interest. The possibilities are endless. Whatever that background thing is, show how it impacted your participation in terms of the actions you took and/or the values you upheld. Make sure you put time into this and don't write it as an afterthought.
THINK ABOUT THE REST OF THE APPLICATION
There is nothing more depressing to me than to look at an MBA application that is hastily put together. Worse still if it is a school that is hard to get into. Worse yet if it is Stanford, where there is a very rigorous approach to application review. The application form, transcript, and resume all play a significant role in the evaluation of your suitability for admission. Given that Stanford GSB is evaluating your intellectual vitality, demonstrated leadership potential, personal qualities, and qualifications, you can be certain that beyond your essays, the rest of the application will be highly scrutinized to determine how you benchmark against these criteria. Some people look at application forms as mere forms. I look at them as opportunities to provide admissions with as complete and impressive presentation as one can. The reason admissions made the application was because they need the information to make a decision about you, so don't provide something that is done at the last minute. Stanford expects that you will take the application seriously. The worst thing you can do is treat this section as a last minute thought.
In the employment section, clients frequently ask me about the question, "What is your most significant professional achievement?" which is required for each position held. I suggest you focus on the situation at work where you had the greatest impact. Where did you add value above and beyond what would normally be expected of you? Sure you may have participated in some engagement that was big but if your role was routine, that is not what you want to mention. Focus on something that required you to take initiative and/or where your impact was beyond the expectations of your organization.
ONE PAGE RESUME PLEASE
Stanford really does prefer a one-page resume!
For a one-page resume template, see here. This is the resume template that many of my clients admitted to Stanford and other top programs have used.
Along with the essays, the Resume and Employment History are the most critical documents that you control. Both should present you as effectively and honestly as possible. These two values are not in conflict: Be honest, be thorough, and do not be humble. You are being judged by your professional experience and this is where they get your complete record of it. Since Stanford generally prefers a one-page resume, my suggestion is to provide that if at all feasible. You can always provide any supplemental information in the Additional Information upload section of the application.
THE BRIEF GOALS STATEMENT IN THE APPLICATION FORM
Please write a sentence or two about what you aspire to do after graduating from Stanford GSB. (Limit 255 characters.)
The answer here should be consistent with whatever you are writing in Essay B. It may simply overlap with content in Essay B or provide a bit of detail that you did not have the word count for. Obviously you cannot get much in 255 characters, so don't worry if this is just a restatement of what is in Essay B. As far as the answer goes, be as clear and specific as possible.
Transcripts
At a Stanford presentation in Tokyo, the admissions officer emphasized that the admissions committee closely reads transcripts. While you don't control the content at this point, you have the possibility of impacting how the transcript is interpreted. Scrutinize your own transcript. If your GPA is high, this is easy. You can relax. If on the other hand, your transcript reveals an unimpressive GPA, some very low grades, gaps in study, or anything else that concerns you, you had better figure out how to address in the Additional Information section.
Additional Information: Use it or don't use it, but don't abuse it.
"Additional Information
If there is any information that is critical for us to know and is not captured elsewhere, include it in the “Additional Information” section of the application. Pertinent examples include:
- Extenuating circumstances affecting academic or work performance
- Academic experience (e.g., independent research) not noted elsewhere"
If you read the above, it should be clear enough that this is the place to explain anything negative or potentially negative in your background or to provide additional information that did not fit in the space provided elsewhere. DO NOT USE IT FOR ANY OTHER PURPOSE. Yes, you may have written a great essay for Tuck, Wharton, Harvard, Chicago, NYU, MIT, INSEAD, Columbia, or London Business School, but don't include it here. I don't think the categories above require interpretation as they are clear.
If you really have no explanation for something negative, don't bother writing about it. For example, if your GPA is 2.9 and you have no good explanation for why it is 2.9, don't bother writing something that looks like a lame excuse. This is more likely to hurt than help you. In the same vein, don't waste the committee's time telling them that your GMAT is a much better indicator than your GPA (the opposite is also true). They have heard it before and they will look at both scores and can draw their own conclusions without you stating the obvious. That said, if you have a good explanation for a bad GPA, you should most certainly write about it.
ALMOST EVERYONE HAS SOMETHING THEY WANT TO EXPLAIN. It might be small or it might be large, but if you don't give your interpretation of something that may look odd in your application, why assume that someone reviewing it will interpret in a manner favorable to you? Your objective is to always provide the admissions reader with an interpretation, especially of something you think is relatively obvious and potentially negative.
Activities
This section is important. Of course, some applicants will not have much here, while others will have a plethora of things to mention. In any case, provide the best answer you can. Use your judgment about what to include. The above instructions make it very clear that Stanford GSB is not looking for quantity. Give them quality and don't mention anything that will show your lack of commitment: If you joined a lot of organizations for a really short time and did nothing, I don't think that it will help you to mention it. Please keep in mind that there is no perfect applicant, just like there is no perfect human being. If you have had to work 100-plus hours a week since graduating from university and your idea of extracurricular activity is sleep, don't assume that not having any great activities will hurt you. Admissions will evaluate your whole application. I have had the opportunity to work with great applicants who were admitted to Stanford GSB, and I can say none of them were perfect, but what they were able to do was present themselves as honestly and effectively as possible. Some had amazing extracurricular activities while others really did not have much worth mentioning.
Finally, I plea with you to give yourself enough time to do a first class job on the entire application. I can't guarantee that doing a great job on the application form will get you into the Stanford Class of 2026, but if you make it part of your overall approach to applying, it will not hurt either. Given the central importance of the resume to the interview process at Stanford, it is critical that you give that document the time and attention that it deserves. Getting into Stanford GSB is simply harder than getting into any other MBA program, but if it is where you want to go and if you think you fit there, commit to putting a significant amount of time into making a great application. Best of luck!
