This review is for Mark Sullivan and the Manhattan Prep Advanced Course.

I started studying for the GMAT in October 2017 and used a variety self-study resources. I made my first GMAT attempt in February 2018 and scored a 700 (Q43/V42). I was slightly disappointed because my goal score was 720. But I figured I was close, so I hit the books again focusing solely on quant for another few months, and took the test again in May 2018. I scored a 680 (Q44/V39). I was incredibly frustrated and I was losing faith in myself. This is when I decided to call Manhattan Prep, looking for a private tutor.

While on the phone, they informed me of Mark Sullivan's Advanced Course, so I decided to give it a try. This was the best decision I could have made. I would highly recommend this course for anyone who needs help getting from the high 600's to the low/mid 700's.

Mark's approach was a complete game-changer for me. Quant problems had always really intimidated me, but after studying with Mark I felt like I could dismantle any problem. He taught me to focus on recognition of what the problem was testing, rather than just banging content into my head over and over again. In addition, I was already strong in Verbal, but Mark was able to help me develop consistency and speed better than ever before by teaching a rules-based approach that supplemented my ear.

I was calm and confident going into my third GMAT attempt, and I came out with a 730 (Q47,V44)!!!

After 10 months, 14 practice tests, and two real tests, my third and final GMAT attempt was a success thanks to Mark.

I worked with Heidi Granner during the Fall 2018 application cycle. I purchased the "start-to-finish" package for four schools and it was the best investment I have ever made.

Heidi was extremely easy to work with, always available, and turned documents around promptly - often before the official turnaround window. Her feedback was always clear and insightful. The MBA application process can be brutal, and working with Heidi made the process significantly less stressful. I am extremely thankful to have worked with her.

In brainstorming and writing essays Heidi was invaluable in helping me to clarify my thinking and find my unique stories/experiences. When it came time to interview she had me better prepared than I could have ever hoped for. Overall, Heidi was a crucial partner in my MBA journey and I absolutely could not have done it without her.

Thanks to Heidi I will be attending my dream school, HBS, this fall.
