Fantastic if you practice

What you need to succeed on the GMAT are an endless supply of questions and a recording engine to tell you what subject matters you need practice in. Manhattan provides both of those things in spades. I probably did hundreds of questions over the last month of my studying and barely made a dent in their question banks. With the analytics tool, I could see exactly which subjects I needed to drill on and which ones I could ease up on.

While the course itself was nothing unexpected (from a content perspective), the real value in taking the in-person course comes from being able to email a real person at all hours and get a personalized response to your question. I made a personalized study plan which really brought my score up after the course was finished.

One caveat, the classes tend to go at the pace of the average student which can slow you down or speed you up depending on the class. I was fortunate to have a very dedicated class with lots of sharp students but classes that I substituted were not as fast paced. Props to Isaac (the instructor) for adapting to the speed of our course.

Highly recommended especially for the sheer volume of resources you have at your disposal.
