We’re proud test-prep nerds and lifelong educators, led by a founder with perfect scores and more than 25 years of teaching experience. All of our tutors are experts in every exam they teach, and we hire fewer than 1% of tutors who apply to work with us.
More importantly, we’re kind, patient humans who care about results. If you’re ready to study hard and think differently, we’re weirdly good at this—and we care more than most.
Feedback That Speaks for Itself
These results didn’t come from tricks. They came from learning how to think clearly under pressure.
Ready to apply this approach to your own test prep?
At least two tutors review every application personally to make sure we’re a good fit.
You’ll never hear from a salesperson — just a veteran tutor who will tell you honestly whether tutoring makes sense for your goals.

CONQUER TEST ANXIETY
We offer dedicated one-on-one coaching to help you overcome test anxiety.
Coaching available on its own or alongside tutoring.
You’re not alone, and you don’t have to struggle with test anxiety by yourself. Our team has spent decades working with students whose biggest obstacles aren’t content gaps, but nerves, pressure, and the mental spiral that strikes before (or during) the test.
We understand what’s really going on, and we know how to help you break the cycle of anxiety and test-day underperformance. Whether you’re dealing with perfectionism, overthinking, racing thoughts, low energy, too much energy, or sleep and focus struggles, we’ve seen it — and we’ve helped students work through it successfully.
MBA Admissions
We’ll design a personalized strategy for your profile, goals, and target schools, so that every step moves you closer to acceptance.
We don’t sell expensive, bloated application packages or make empty promises. Our MBA admissions consulting is about one thing: helping you efficiently build an application that admissions committees will actually remember. That means sharper strategy, stronger storytelling, and unfiltered feedback from consultants who care more about your results than about selling you more hours.
We’ve offered MBA admissions consulting since 2008, helping candidates earn admits to HBS, Stanford, Wharton, INSEAD, LBS, and dozens of other programs across the globe. We’re expert storytellers who have seen every type of profile and every admissions challenge, so we know what works and – just as importantly – what doesn’t.
Straight Talk with GMAC
You asked us; we asked the creators of the GMAT & EA. Our exclusive video series tackles the most common concerns we hear from students.
Preparing for the GMAT or Executive Assessment can feel like navigating a maze while blindfolded. Test-takers often have pressing questions about the exams, from scoring mysteries to testing accommodations.
Fortunately, GMAC — the creators of the GMAT and EA tests — have answered all of these questions on camera in a YouTube video series hosted by our own Charles Bibilos.
What Makes GMAT Ninja Different
Experience
With over 100 years of combined teaching experience, our team of experienced GMAT, GRE, and EA tutors has helped students gain admission to every top MBA program in the world, from HBS to INSEAD to ISB. Many of our teachers have earned perfect GMAT or GRE scores, and every one of us has the track record to prove we know this process inside and out. No other online graduate exam tutoring team matches our mix of skill, transparency, and results.
Expertise
We’re probably the only major test-prep company founded and run by a real educator, not a marketer or entrepreneur. We’ve served as resident GMAT Club experts for nearly a decade, and we’re obsessed with helping students think better, not just memorize tricks. If you’ve tried other courses and still feel stuck, we’ll show you exactly why they didn’t work and what to do instead.
Versatility
We can’t stand templates, tricks, or gimmicks. Every private tutor on our team builds a plan around how your mind works. No two students ever follow the same path. We’ll dig deep to uncover what’s really holding you back—even if it’s not what you expected—and we’ll tailor every session and homework assignment to help you build new habits that lead to real improvement.
HONESTY
We don’t promise miracles. We’ll tell you what’s working, what’s not, and what you need to do to reach your goal—starting from the moment you fill out our intake form. That often means at least 15 hours of homework a week, along with a whole lot of introspection. We’re not afraid to kick your butt (politely!) if you’re wasting your time or money. But if you’re ready to show up consistently, your tutor will be in your corner every step of the way.
That’s because it all comes from the heart. We hire tutors who are genuinely kind, thoughtful people, and we’ve used our platform as test-prep experts to raise tens of thousands of dollars for nonprofit organizations. We also happily provide an unparalleled collection of completely free video courses, study plans, and articles, so that we can help everybody crush the GMAT, GRE, or EA — regardless of their financial status.

Personalized Tutoring FAQs
Choosing a GMAT, GRE, or EA tutor is a big decision, and you probably have questions. Here are answers to the things students ask us most often, from how sessions are structured, to the materials we use, to what kind of results you can expect.
The quick answer is that the structure of tutoring depends entirely on each student’s strengths, weaknesses, interests, and needs. You’re (presumably) looking for a tutor because you want somebody who will efficiently teach you exactly what you need, rather than wasting time with a one-size-fits-all class.
Keep in mind that each of the exams we tutor (GMAT, GRE, & EA) are extremely nuanced. We’ll look for the most efficient ways to help you gain points, and that inevitably means different things for different people.
For a deeper look into our tutoring process, check out this video:
For the GMAT, EA, and GRE, we offer dozens of sets of practice questions that we’ve developed over the years, but these sets are only designed as supplements for students who need extra work on certain question types. Each exam has its own unique question styles, and there’s absolutely no substitute for using official practice questions.
So the answer is yes, we do provide our own practice materials to our students. But we would be crappy tutors if we pretended that our materials were somehow better than the materials developed by the people who actually write each of the exams.
Nearly everybody asks this question, and our answer is always the same: it depends.
If, for example, you’ve never touched a GMAT or GRE prep book but dream of admission to Harvard or Stanford, then you might need more tutoring than somebody who is just fine-tuning her approach after months of self-study. If you’ve taken only a single practice test and your score was significantly lower than your goal, then you might need a whole lot of time with a tutor.
There are no shortage of other wildcards: everybody improves at a different pace, some students are better about doing homework than others, and some applicants have set more challenging score goals than others.
So we know that the answer is unsatisfying, but until we know a lot more about you and what you’re trying to achieve, we can’t predict how much tutoring you’ll need. Sorry.
You’re persistent, huh? We like that.
This might be too generic to be helpful, but if you’re looking for improvement on every section of the GMAT, GRE, or EA — and if you’re able to keep up with our recommended workload (~15 hours per week, with two-hour tutoring sessions roughly once a week) — then it’s reasonable to expect your learning curve to “flatten out” after about 12 weeks.
Here’s the problem: your learning curve might flatten out exactly at your goal score, or it might flatten out long before you reach your target score. Or if you’re lucky, you might even overshoot your score goal if you study for 12 weeks. So it isn’t unusual at all for a student to reach their goal in less than 12 weeks, or for us to discover that it’s going to be a long, hard, uncertain fight to achieve a particular score.
So we can’t predict exactly how many sessions you’ll need. We can, however, promise to be 100% honest in our assessment, even before you sign up for anything. After you fill out our intake form, at least two veteran tutors will assess your situation. From there, we’ll do our very best to give you a sense of the road ahead before you make a decision about tutoring.
This is a big part of how we’re different from other tutoring companies: all of our tutors are trained to the same ludicrously high standards, and we all collaborate frequently to make sure that we continuously improve as tutors. We all use the same materials and employ the same philosophies, and we’ve all trained — hard — to become nimble in our approach to tutoring.
We’re also painfully selective in our hiring process: in our most recent hiring rounds, we extended offers to four tutors out of more than 3000 applicants.
Sure, we all have different personalities, but we work tirelessly to be similarly great at our craft, and we’re as unified as a collection of tutors possibly can be.
In other words: if you think Charles has some secret sauce as a tutor, rest assured that he has already shared every bit of it with the rest of the GMAT Ninja team.
