I took my 4th gmat prep on sunday, and I can't seem to break the 650 barrier. I had different RC passages and only about 5 total questions that were the same from previous tests and I thought I had done well.
I did much better on the Q, even though I ran out of time, but did worse on the Verbal, which the opposite of how I have been doing. I find it really hard to figure out what I had screwed up on in the verbal since the gmat prep doesn't break down your weaknesses or tell you what difficulty of questions you didn't do well on.
I was a little discouraged, but I decided to forget taking any more gmat prep tests and just focus on SC and some Q problems, since it doesn't really help you on weaknesses other than give you an idea of the length of the test. My test is this thurs.
I had taken a test on sat. and tallied about 6 hours of working on the gmat for that day, so I think my brain was tired on sunday.
How the gmatprep can score you without giving you explanations to problems you missed is beyond me. I guess they want you to buy their gmat 800 book, which I ended up doing, but mostly I have found these forums to be the best help in solving these problems.
I am hoping things comes together on thurs and my brain is well rested. I actually haven't taken any practice tests with the AWA.
