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.
