The way he structures the tutoring content is also incredibly helpful; instead of forcing you to re-learn every math concept that the test may throw at you, he makes sure you only focus on the most important things.
The personalized study plan he developed really helped me to focus on improving the areas where I was struggling. During our sessions, I was always impressed by how he clearly and simply explained even the most complex solutions.
The bespoke lesson planning, trove of study material, and friendly nature of the Atlantic GMAT team are well worth the (competitively priced) cost.
He had just the right tricks to help me boost my verbal score, especially the CR section, which was my weakest point. I couldn’t believe I was scoring in the top 6% in my verbal after a month and a half.
I really appreciated Andrew’s approach – it didn’t feel gimmicky and reliant on “strategies.” It was just about learning the key material, not overthinking, and practicing good habits.

In about a month of self-study Matt earned a 770 on the GMAT with a 50 on the quant and a 46 on the verbal, ringing in above the 99th percentile on his first attempt. It’s not a surprise that he has a degree in Applied Mathematics from Yale and is currently working in artificial intelligence.
Having spent 5 years in the trenches helping university students pass calculus, Matt is a steady, patient, and organized teacher certain to get your GMAT house in order. His laid back style makes it easy to learn from him.
Although a math whiz, Matt is just as comfortable helping with the most challenging GMAT quant as he is solidifying fundamentals. No slouch at verbal, he was the editor of The Yale Record, one of the oldest undergraduate publications in the country.

In two months, Matt A. helped me increase my score by 100 points to reach my goal score! I had previously used a self-study course but it did not translate into an increased score or consistent results.
I had a wonderful experience with Atlantic GMAT! Matt was a great teacher and resource during my studying.
I worked with Matt over the course of almost three months and was able to achieve my “reach goal” score – from day one, the daily work and weekly lessons/check-ins helped me hone my abilities.
Matt, was incredibly personable and stuck with me over an extended journey to get me to a 730!!
