I may have to take up that offer in preparing for my GRE Math Subject test. I heard GRE Math is challenging even for "math people."
I disagree. I feel that GRE math is not even close to GMAT math. I scored 790 on GRE math and I thought GMAT math would be a breeze. I was wrong!
GRE math has a lot less tricks than GMAT math. You should have no problem.
JC, Congrats on your score man, truly AMAZING!
