Thanks guys!
Regarding my preparation details.
I prepared for approximately a month and half. Mostly a couple of hours every day on week days (since I work full time) and a little more on weekends.
I am an engineer by profession so quant was never that big an issue for me. Even then I went through each and every question of OG 12 at least twice. Then I went through most of the tough ones posted on GMAT Club forums.
My biggest issue/concern was SC portion of verbal. So spent most of my time working on that. Once again went through each and every question of OG 12 at least 2-3 times. Moreover I went through each and every thread in the SC section of GMAT club and I have to say that it was quite a learning experience. Excellent questions and even better explanations/discussions. Must for everyone preparing for GMAT.
I took only two practice tests, the ones provided by GMAC.
Took first test two weeks before the exam (720-Q49,V39). But I got most of the SC questions wrong.
Took second test one week before the exam (750-Q50,V41). SC improved but confidence was still lacking.
Hope that helps. Best of luck to everyone preparing for the exam.
