GMAT Tutors, Events, and Resources

I'm an experienced GMAT tutor who has tutored hundreds of students over the past five years. My clients have been admitted to Harvard, Yale, MIT, Cornell, and more. I have a 98th-percentile score on the GMAT (750 original version) and a 99th-percentile score on the GRE (335). My approach is straightforward, kind, and effective. We'll spend our time on the skills you need to build to succeed, and I'll always be honest with you about your progress. I'm happy to provide comprehensive instruction on the entire exam, occasional help for self-study, or anything in between.

My intuitive, common-sense approach to the GMAT has helped numerous students get top scores since 2011. I emphasize comprehension rather than memorization: Instead of just giving you rules to remember, I help you figure out why they work. There's no magic formula that makes the GMAT easy, but with my techniques, it won't feel too hard. A good GMAT tutor should meet students where they are, and I always strive to do this. If you know a concept but struggle to apply it to certain tricky problems, I can help you with that. Alternatively, if you need something explained from the ground up, I can help with that too. I am flexible enough to work within your mental framework, rather than imposing something completely unfamiliar. My goal is to find explanations and methods that work for you, even if they aren’t entirely standard. I'll make sure to warn you if you're heading in a wrong direction, but for the most part I view GMAT tutoring as an opportunity to help you leverage skills that you already have. I've found this to be a very rewarding process, and I think you will too!

Andrew never thought he'd be an influencer...but here we are! Andrew has shared hundreds of test prep videos with his 30K TikTok followers, but nothing replaces the energy of live instruction. With a 770 score, Andrew knows a thing or two about the GMAT. However, just scoring well on a test doesn't make someone a good instructor. 10 years of test prep experience does. Before moving into grad school testing, Andrew was an in-demand SAT instructor on the Upper East Side of Manhattan at some of the most selective high schools. He has taught the in person, online, and on campuses such as USC, UC San Diego, and CSU Northridge. He loves helping students reach their highest potential and conquer their fears!

I’m a deferred MBA admit to the Kellogg School of Management and scored a 715 on the GMAT Focus Edition — a 99th percentile result — after just under three months of self-prep. My goal as a coach is to help you optimize your study time, focus on high-yield strategies, and avoid the common pitfalls that waste time and lead to burnout.

My one-on-one coaching for GMAT Focus preparation covers all tested sections: Verbal, Quantitative, and Data Insights. I follow a practical, results-oriented methodology, focusing on core concepts, exam-specific strategies, and efficient execution techniques required to achieve a competitive score. Sessions include a detailed explanation of formulas, exam vocabulary, mathematical terminology, and structured approaches to time management. Based on my coaching experience, candidates starting from zero typically require 30–40 hours of instruction to cover the full scope of the exam in a thorough and effective manner.

I studied for the GMAT while working long hours, so I understand how frustrating and tiring the process can feel. I ended up with a 740, and since then I’ve helped friends and colleagues prepare - mostly by figuring out where to focus, creating realistic study plans, and talking through the concepts they were stuck on. I don’t believe in overcomplicating it. I just try to make it doable, clear, and a little less lonely.
