gre hell

[quellers]

So I'm scheduled to take the GRE on the 25th, which is now a week-ish away. I'm doing fine with verbal, but the quantitative section is really killing me. I haven't taken a math class since high school, haven't done math without a calculator since middle school, and generally feel math illiterate. I've been working primarily with Barron's GRE book, but I have also tried 5th - 8th grade math workbooks to brush up on the basics, The Ultimate Math Refresher book, and some cd thing called Math Advantage. I do the problems at the end of every Barron's review section, but never even get half of them right. I read the explanations for the ones I get wrong, but I don't think that helps. On every practice test I've taken (and I've taken many, including powerprep), I can't get above the low-400s. I'm beginning to wonder: have I reached my limit? The only hope/excuse I can think of is that I've been working 2 jobs until yesterday and maybe haven't been focusing hard enough on GRE prep. Now I have a full week to devote to math and nothing else. Do you think it's possible to raise my score between now and the test? My goal at this point is to break 600 - is that even realistic? What have you done/would you do in my situation? Any general advice? I'm way too stressed about this. :-(

eta: I took a powerprep test again for the first time in a while and got a 470. It was encouraging :-) Also, number2.com is proving super helpful. Thanks.
