GMAT Tutors, Events, and Resources

I’ve been teaching the GMAT since 2006 and the GRE since 2009. Over the years I’ve created a vast collection of slides, notes, and handouts for you. But I don’t believe in being complacent – in fact I’m constantly trying to improve through further study, research, and innovation. When I worked for a test-prep company I wrote a 270-page manual on Verbal problems, to help train the company’s teachers and textbook writers. To keep my math skills sharp, I regularly take college-level math courses. Right now I’m also redesigning my whole Critical Reasoning curriculum. For me the most exciting thing about teaching is that moment when a student suddenly understands a concept. To make those “aha!” moments happen, I carefully tailor my lessons to each student’s knowledge level and learning style. I encourage you to send me questions before each session, so that I can prepare a lesson plan for you. After each lesson, you’ll get a PDF document with notes on what we just covered.

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!

GMAT success requires a high-level operational mindset, razor-sharp executive functioning, and an advanced command of data-driven decision-making under tight constraints. Having guided elite candidates through complex career pivots and highly selective business school transitions for two decades, I understand that traditional, rote instruction completely overlooks the psychological discipline needed for this exam. I specialize in refining cognitive strategy for transitioning executives and high-achievers who have hit a score plateau. By analyzing how your brain naturally processes complex data modules and handles pacing pressure, I design a personalized strategic blueprint that optimizes your performance when the clock is ticking. Once we have gained a clear understanding of strengths and weaknesses in regards to the test structure and question types, we establish a set of general navigation rules to practice, while zeroing in on specific areas of the test to eliminate wasted time and structural bottlenecks; Finally, we build up decision-making stamina until it is unshakable, and reclaim learning agency for long-term career mastery!
