Materials & Instructor Overview Were Very Helpful

I found the Manhattan Prep test books and the overview of the GMAT that my instructor provided to be very helpful. I personally got more out of the books and the first class than I did the remaining eight classes, but everybody learns differently and I have a more independent learning style. That being said, my instructor (Keith) was great. He was supportive, patient, and encouraging. Even if I didn't find the class to be particularly helpful, I think access to an instructor is invaluable. If nothing else, purchase the Manhattan Prep Test Books and work through them on your own. I can't emphasize how helpful and manageable they were.
