I've been preparing students for the GMAT Focus for over 10 years. I've worked with 400+ students, achieving a median score of 665 (equivalent to ~720 on the old GMAT, 94th percentile) with improvements of up to 400 points. All students who completed the full admissions journey were accepted into their target business school, including M7 programs (Harvard, Stanford, Wharton, Columbia, Booth, Kellogg, MIT Sloan) and top European schools (LBS, INSEAD, HEC Paris, Bocconi, IE, IESE, Cambridge, Oxford). I hold an MBA from SDA Bocconi and Columbia Business School, a degree in mechanical engineering from Politecnico di Milano and the University of Illinois, and I have experience as a university teaching assistant. I also prepare for the Executive Assessment (EA), the SDA Bocconi Executive MBA admission test, GRE, IELTS, and TOEFL. Lessons cover all sections of the GMAT Focus: Quantitative, Verbal, and Data Insights. I teach you to think under pressure, manage your time, and spot the patterns the test uses against you — because that's what the GMAT actually measures, not just how much math or English you know. We work with a hands-on approach on everything it takes to score competitively for top business schools: techniques to optimize your pacing, strategies for every question type, and realistic exam simulations. The other key area we focus on, and that almost no one addresses, is the psychological side. Test anxiety and freezing up on a tough question are real — and they cost you far more points than a formula you think you've forgotten.

Hello and welcome! With a GMAT score of 740 (97th percentile), I successfully earned admission to the University of Oxford, where I completed dual Master’s degrees—an MBA and a Master’s in Public Policy. My GMAT preparation focused on mastering the essential maths rules, logic, and language skills needed for success, a method I now bring to my coaching. I understand the challenges of competitive admissions and the role the GMAT plays in standing out. Whether you're aiming to improve your quant skills, sharpen verbal reasoning, or develop a clear test-taking strategy, I offer actionable, tailored guidance to help you achieve your target score and reach your academic goals.

Note: Due to high demand, I do not offer free intro calls or discounted sessions. Thank you for understanding. I didn't just walk in and get a perfect score. My first score was in the 50th percentile. I studied my way to 99th percentile, so it's definitely possible. I have a 99th percentile score on the GMAT, GRE, and SAT, and have taught for Manhattan Prep, Kaplan, and Target Test Prep. I don't just teach the content. I teach how to think. I have a Masters in Education from Harvard and have written a book on the mental approach to standardized tests.

I have been tutoring GMAT Verbal for 10 years and have very clear and precise strategies that have helped dozens of students achieve their goals. As a lover of language, a teacher of English, and a writer myself, I have the skills to integrate all things verbal with the necessary standardized test taking methods.

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 scored a 755 (100th percentile) on the GMAT Focus Edition, with a V90, and tutor across all three sections, though I have the most experience with Verbal and DI. I like to think of the GMAT as a test of decision-making under time pressure, not raw intelligence. My emphasis is on question-solving strategies — how to read efficiently, eliminate decisively, and manage time without rushing or freezing. I’m very hands-on and adapt my approach to how you think, whether that means simplifying complex ideas, fixing timing issues, or helping you gain confidence where you’ve been second-guessing yourself.
