My story....I needed a 500+ Overall, 30th percentile in both Quant & Verbal, but the Quant sunk my ship today. I'm not sure what happened, I've been practicing for about 2 months and generally score 500-570 Total, 40th percentile+ in Quant. The Quant problems appeared to be easy but for whatever reason I was not able to apply my practice during the test. I used the following: GMAT prep software, Kaplan Quant Book, and the Princeton Review. I found the official GMAT Verbal to be much easier than expected and only used the Princeton Book for studying this portion. However, I'll need to find other resources for the Quant because the 16th percentile did not meet requirements.
Anyways, I've heard a general College Math course is good for GMAT preparation. Has anyone heard this?
