Thanks everyone for the support. The study materials I used are OG 11, Kaplan GMAT 2010: Strategies, Practice, and Review (978-1-4195-5294-6), McGraw-Hill's GMAT 2010, w. CD-ROM (978-0-07-162416-9), and GMATPpre v2. I did all the questions in all three books at least twice. For GMATPpre v2, I got like 570-620, depend on my luck. I mean 550 should be a reachable goal with those study materials. I am not asking for 600 to 800.
I have one last hope before my application deadline. This hope will be in one month. As for the prep courses and
MGMAT books, I just don't have money to afford them, and time to complete them. They are too expensive in my case. All my study materials are free from internet and friends.
Do you guys have any suggestion that what should I do before my last hope?
Thanks everyone again
