This review is for:  Manhattan GMAT 9-Session Prep Course | Location:  Washington, USA | Taught by:  David Chong
I signed up for a 9 week Manhattan GMAT course after trying to study on my own. I realized that I needed to sign up for a course and I learn better in person (it also ensures that you go to class and don't procrastinate watching videos online). I started with a practice score of 560.

David was a great instructor and the course really provided me with the tools to understand the test and the tactics I needed to vastly improve my test score to 710 and also feel much more confident going into the test. On top of the great in-person instruction, it was a great resource to be able to review sessions online. There are also a ton of other resources and study aids on their site. I probably only accessed about a quarter of them!

I can't recommend Manhattan GMAT and David enough!

From Good to Great with MGMAT

I highly recommend the full set of Manhattan GMAT self-study materials, as well as MGMAT tutors. In particular, MGMAT helped me raise my quant score significantly thanks to its difficult Quant sections on its online CAT exams.

After several months of intense self-study using prep materials from other providers, I first took the GMAT in March 2013 and scored a 700. I debated sticking with the score, my quant/verbal split was very skewed (63rd percentile quant/93rd percentile verbal), and I felt that with more effort/dedication through a structured prep program I could bring up my quant score.

Initially I enrolled in a full 9 week MGMAT course, however when I took a diagnostic test and discussed the results with my instructor, he recommended I consider tutoring instead and focus on quant alone (since my verbal score was already high). MGMAT allowed me to transfer my course credit with relatively little hassle, and I met for ~5 hours of tutoring spread over 2 months.

My tutor did a great job working through difficult problems with me, helping me develop strategic approaches to test-taking, and analyzing the results of my practice tests to give me personalized feedback and problem sets based on my weaknesses. In particular, my tutor helped me understand the importance of time management on the Quant section, and gave me several useful strategies to improve in this respect.

I retook the GMAT in Aug. 2013 and scored a 760, with an 81st percentile quant/99th percentile verbal split. I think my improvement from a good to great score is a result that speaks for itself in terms of the quality of MGMAT materials and instruction. Thanks Manhattan GMAT!

David was an excellent tutor and helped provide the feedback I needed. He broke down the concepts and provided tips that were very helpful during the test. He was very available to answer questions and was able to really hone in on my weak points, specifically probabilities and combinatorics. He also made the GMAT less of a mystery by explaining how the scoring process worked and what the best strategy was for time management, difficult problems, and boosting your final score. In my case, I knew that I wanted to boost my quant as much as possible so we focused on that. He gave me hundreds of problems to do and in the end it paid off.
