Just wanted to give everyone a quick thanks, the forums on here helped a bunch and you people kept me sane. I took my GMAT today - no more studying!
I got a 740 - Q49,V42 (the percentage breakdown was 97,88,95 for those interested in comparing previous tests).
I thought that the quant was easier than GMATPrep and that the verbal was about the same.
Although I came from an engineering background, quant was actually my weak point (when I started preparing I was in about the 70%). I think part of it is that we deal with much different subject matter and part of it that I had an ego and thought I should just be able to do the quant without trying. One of the things that I suffered from is that I didn't really like going over my mistakes and I never really did a good job with that. In the end I sort of hoped for the luck of the draw in getting questions that I knew (which sort of worked out, but there were a couple of types of questions I'd gotten wrong before that I did see).
MGMAT probably helped me the most with quant, I did the
MGMAT tests for quant about 12 times.
Verbal, even though I don't really like it, was always my strong point. The only advice I can give is to really figure out what the point of the question is. I was thinking about law school for B-school, so I think the LSAT prep material did really help me out here. When I first started practicing LSAT, I took notes religiously as I read the question, as I moved on, I could still pick up the same pieces of info without writing it down, which helped speed. I'd recommend that approach. One other thing that I think helped me was that I always tried to cross out an answer if I could find even the slightest thing wrong with it. Sometimes I ended up with them all crossed out and had to start over, but more often I ended up with one left. I did have to study sentence correction, but all I did was go through
MGMAT SC and then did a bunch of practice problems.
Finally, as people say it is worth it to retake the GMATPrep over and over until you're scoring much higher than the score you'd like. What you need going in is confidence. I felt good going in today and I frankly wasn't really nervous, just ready to get it over with. Having inflated scores in GMATPrep tests helped out with that.
Make sure you read tips about the testing procedures (breaks, etc) - this saved me from eating into valuable quant time.
