I'm just starting to study for the GMAT. I took a diagnostic to judge the level I'm currently at. I got a 710 (Q-50, V-37) on the ETS Powerprep 1. I found that managing time wasn't too much of a problem. However, I made several mistakes on the verbal section that I shouldn't have.
I haven't really looked at any of the books on studying for the GMAT. I just purchased the official guide 10th edition and 11th edition from Amazon. In addition, I've got some old editions of Kaplan
and Princeton review
that I'm going to start looking at seriously.
Are there any other books that would help?
