If you buy a

Manhattan GMAT book, you get access to 6 CAT exams with detailed answers.

If you are looking for GMAT Prep question explanations, you can search this forum. It may have been discussed before.

I'm just looking for extra practice and also an accurate prediction of where I will score. I scored a 620 on the

Kaplan test, and then a 710 on the GMATPrep a little later after more study, which I'm not 100% confident in, because I seemed to have gotten like 40% of the quant section wrong. I seem to be stuck in the question review and find a way to get back to where it shows my score.

I've already read the

Princeton Review Cracking the GMAT book, and done just about all of the questions in the Official Gude for GMAT Review and Quantitative Review.

Would you recommend buying the

Manhattan GMAT book, given that I have already worked with these other 3 books?
