Hi. I found this site just a little while ago and it's great. I look forward to contributing what I can as the process goes along...
I finished PowerPrep's practice test #1 and scored a 570 (Q 31; V 37) without any studying, test-taking strategy, etc. It was taken completely cold so I could see where I stood and what I need to work on (I took the GRE about five years ago so this isn't totally alien to me. Come to think of it, I'm not really spooked about having to take another test.

)
The average score for students in the two part-time programs I'm looking at (George Washington and Va Tech) is 600-620 so a little improvement is in order, especially on the math. I can smoke the verbal section (scored 93rd percentile on the GRE with minimal effort) but I am not that mathematically inclined.
With that:
1. How much higher can I expect my score to go with some studying and test-taking strategies? I don't need a 700 but what's realistic?
2. Can anyone suggest some good study guides for the math portion? (Tehe math forum looks like it will be a great help.)
