Mark Sullivan is a great instructor!

Before I started working with Mark Sullivan, my dream to get into an M7 program was just that - a dream. I scored a 620 on the practice test and I needed to significantly increase my scores to be in contention for a top program.

I was in a general management position that could be all-encompassing - so I knew that I needed a structured program to keep the ball rolling, that was also compatible with my travel schedule. Taking all this into account, the live online program was the perfect fit for me.

From day one, it was an absolute pleasure working with Mark. He was friendly, approachable, and was always enthusiastic about the subject matter. As a 790 scorer, he had lots of tips and tricks to solve problems more effectively. He helped us reframe "problems" to look at them as "puzzles", and challenged us to find the quickest way to the destination. In addition to the Manhattan Prep material, he had tons of additional tools, such as the "arithmetic game" to sharpen our skills. Also, he worked with us to put together individual study plans for us to increase our scores.

He was a great teacher, and a pleasure to learn from. Would wholeheartedly recommend him to anyone looking to sign up for GMAT classes.
