Mark Sullivan is Sublime - 770 Score
I took the Manhattan Prep Advanced Online course with Mark Sullivan, and it was absolutely outstanding, 10/10. The course itself is great for those who can self-study or have taken previous courses and are past the basic "content" phase and moving more into strategy and consistently difficult questions. Mark has all the requisite intelligence and background to clearly demonstrate mastery of every possible nuance of the material. Other instructors might match him in this regard, but no one comes close in social IQ. He understands how to explain, how to probe and encourage, when to be patient, when to speed up. He is engaging and comical without being distracting. He is totally selfless with his time and thorough with his explanations but avoids dragging class on for too long. I experienced all these problems and more with other highly qualified, well-reviewed instructors. For context, I also took Veritas Prep Online course with two different instructors. Mark is in a league of his own. An absolute pleasure to work with from beginning all the way through to post-exam assessment and feedback on follow-on steps. I was unsure about spending hundreds of dollars on GMAT prep initially, but with Mark, I see that as a sound investment.
