I bought a few of the popular GMAT study guides and took the test a couple of months ago. In general, I found the practice content did not reflect the difficulty of the actual GMAT. I was very disappointed to get a 650 on the exam, as I was aiming for a 700+. I bought a couple books that claim to review the hardest questions (Gmat 800 by Kaplan) I studied these books for about a month and a half and then took a couple of the free practice exams online (Kaplan and Princeton Review) and received 680, 670 respectively. I am scheduled to take the GMAT again in a couple of days. Since the chances don't seem very good that I'll break a 700, I'm thinking that it may be a better idea to skip the test and re-take it after taking a comprehensive course. Should I wait until I'm better prepared, or take it anyway? Does 650, 670, 700 look worse to business school admissions than 650, 700? Thanks.
