Thanks for the reply...
I did three of the Kaplan tests on the CD. 640 was my highest score, which is pretty good according to what I've seen other people score.
[If you have not done the OG prior to taking the PP, your score should be very close to the range you have mentioned. The third and forth attempts of 770 and 760 are not valid since PP has only questions for 2.5 tests - while doing those you were doing repeat questions. Though the results are good - you have done a good analysis of the questions you have missed. ]
I assume you mean official guide (OG). When I took Powerprep's test for the first time, I had studied and worked on Kaplan's and Princeton Review's. The first test was a 700, and I don't remember seeing any of the questions before, although I had worked on some of the OG's problems. Same for the second test (650- 50Q, 31V). You are right, I know that the last two attempts are not valid because I had already looked at some of the questions.
Is there another good CD out there? How about ARCO's or something like that? Still, none of the sample tests I have taken include probability(except for a few very basic questions).
The $200 are not a problem. I don't mind spending them again and retaking the exam. The thing is that now I don't know if I am ready (I thought I was). I am sure that I blocked because of being nervous...that definetely had a lot to do with it (although again, I don't like to use excuses). I think if I can keep a clear mind going into the test, I should do better. However, being limited to 5 exams per year and only once per month limits my options. I just want to "get it over with" (classic quote from my boxing days!)
My other concern (besides whether or not I have prepared enough) is that I could probably be torturing myself too much: I have an exam tomorrow-my final class of another master's, the thought of being behind schedule on my thesis, and having to prepare for the GMAT.
Thanks guys...I think I'll sign up for next month, although I moght not put as much effort this time around as I did the first time (I can't afford to have the GMAT control my life, you know?)
Thanks for the advice. I think I need to relax and not be as persistent...who knows...
