Gmat Prep Courses

Need help, I'm so confused about what course to take GMAT preparation ...?

Do you have any entry on preparatory courses for the GMAT, which is worth the time and investment? I want to score in the top 700 and I am the beneficiary of good test, only I want the face to face review. I appreciate your input ... thanks!

I agree with you that a face to face review is a good way to reconnect with the fundamental concepts of evidence (and like most, I often learn more effectively with personal interaction). I am not the test taker wrong, but when I started to look over some materials GMAT, I saw many concepts that I had not seen since high school. On the recommendation of a friend, I went with Powerscore, and was a great class. The instructor was an expert in total with the test, and its approach is understandable and effective. When it came time for me to take the GMAT, I was very confident because I felt I already had a clear idea of what was to be on the test. Finished with a 770.

What GMAT Test Prep Course is the best? I'm looking Testmasters, Kaplan, Princeton Review ... any others?
