Manhattan GMAT class review

I felt this course was not very helpful in terms of math. They did not provide adequate enough math problems to help solve the Advanced Math problems. It was not until recently that Manhattan GMAT provided the Advanced Math coursebook that I felt was more in line with actual math problems I saw on the real exam. Also, the Number Properties course was very useful.

Generally speaking, I believe each in-class course that is taught my Manhattan GMAT depends on who the instructor is, and what strengths the instructor has. I did not like my initial instructor bc he was very poor at explaining verbal explanations and so I switched into a different course and like my teacher MUCH better.
