What Makes GMAT Ninja Different

experience

With over 100 years of combined teaching experience, our team of experienced GMAT tutors has helped students gain admission to every top MBA program in the world, from HBS to INSEAD to ISB. Many of our tutors have earned perfect GMAT scores, and every one of us has the track record to prove we know this exam inside and out. No other online GMAT tutoring team matches our mix of skill, transparency, and results.

Expertise

We’re probably the only major GMAT test-prep company founded and run by a lifelong educator, not a marketer or entrepreneur. We’ve been the 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 what didn’t work — and what to do instead.

Versatility

We can’t stand templates, tricks, or gimmicks. Every private GMAT 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 won’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 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 GMAT 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, regardless of their financial status.

Each tutoring session lasts 2 hours. We’ll take payment for the first session in advance, and for any further sessions, you’ll pay as you go after each session. We don’t offer packages or bulk discounts, because we strive to minimize the number of sessions you’ll need — and we never want you to pay for more tutoring than you’ll use.

What Our Students Ask

Personlized Tutoring FAQs

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.

How to get the most out of GMAT tutoring

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 official 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 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 — 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 really 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.

We can promise this, though: we’ll provide honest assessments every step of the way, even if it’s not what you want to hear. So if you start working with us, we’ll do everything we can to make sure that you understand where the process is headed, and what the prognosis is for improvement.

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.
