Don't know the prices, but many consider the Manhattan GMAT course the best course. Also, Knewton guarantees a 50 point increase. I would recommend studying a lot on your own and then figuring out the areas you need help with and use the class/instructor to really focus on your weaknesses.

Thanks a lot for your reply. I am planning to study by myself too. Which materials do you recommend in order for me to do my own studying? Thanks again

For Verbal:

Manhattan GMAT Sentence Correction
Powerscore Critical Reasoning Bible

For Math:
All of the Manhattan GMAT math books (5 in all)

If you are planning on going with Manhattan GMAT for your class though, you get all of the books when you enroll in their class, so instead of getting the Manhattan GMAT sentence correction guide, buy the powerscore Sentence Correction Bible instead. I really can't recommend a replacement for the math books, because their math books are viewed as the standard for GMAT math prep. I have heard good things about EZ solutions though.

So Manhattan GMAT does not offer the powerscore Sentence Correction Bible?
Also you saying that they have about 5 books in total for the math section?
what was your experience with the GMAT? How did you do?

I haven't taken it yet. What I can say is that I went from scoring around 550 with the practice test to 700 by using the Manhattan GMAT materials. You can go to the "I just beat the GMAT" forum on this board and you will see most of the people that scored above 700 will have used multiple books from Manhattan GMAT.


The Powerscore Sentence Correction Bible is a different company (Powerscore), Manhattan GMAT has their own sentence correction guide which many consider the best guide available.

I just found out that it cost about 1400 to take the GMAT course at Manhattan GMAT. I still want more opinion on whether is worthy to pay that kind of money?? Thanks
