Most GMAT students aren’t failing because they’re “bad at math.” They’re failing because they’re using a broken process: random practice, shallow review, and no repeatable method.
The Study Reset gives you the exact foundation I use with students to build real improvement. You'll get the first 6 chapters of The GMAT Mentor, including the core study framework and the first strategy chapters for Problem Solving, Data Insights, and Data Sufficiency.​

This book calmed my test anxiety.
A friend recommended Mark's book and I really like how his style made me feel more at ease and definitely less anxious about the test. The problems feel extremely realistic and the structure was logical. Now I feel like I have a plan to beat the Quant and Data Insights section. Just know that this book doesn't cover the Verbal section of the test. I definitely would have loved to hear his insights on the Verbal section, too.

Best GMAT / EA Prep book!
Highly recommend this book for anyone studying for the GMAT or EA. I used this while prepping to eventually be accepted into Columbia business school.
Mark is an expert tutor and has years of experience in the field. I highly recommend this book for anyone looking to save time studying for the exam and I also highly recommend booking some tutoring sessions with Mark. He is awesome and the problems are 1:1 what are covered on the real exam!

Actually helpful!
I’ve worked through a handful of test-prep books at this point, and this is the first one that actually made these concepts click for me. Instead of just dumping formulas or giving surface-level explanations, the author breaks down the logic behind each question type in a way that’s easy to follow. I never felt lost and saw some real improvement in my score!
