Great course and books

I took the ManhattanPrep classes early in 2016 and high recommend the course. The classes and material were great and helped me study to take the GMAT and get a score over 700. The books and online material are very streamlined so you study in the most efficient manner and don't waste time learning or doing things that won't help. Our instructor, Christine, was a lot of fun. Make no mistake though, the study and homework workload is heavy. I'd say 10-20 hrs per week.

Their website was particularly useful. They have online classes that cover the class content and can also be used for review. The interactive classes have excellent exercises to help with the AWA and IR. And finally they have the online CATs and a system to take the individual questions/tests online, review answer explanations and analyze your performance on specific types of questions so you can work on improving weak areas.
