please I need help

I took the gmat over 3 weeks ago, it was a nightmare 450. I never got that score while using Gmatprep. SO I registered again for today, re-read Kaplan, used Manhattan gmat (I'm not somewhere close to anywhere where there are gmat classes). My score went up again. I did 2 tests this week on GMAT prep, first one 640, yesterday got 460. So I tried to calm down and relax, not read, revised this morning. I just got out, I got 500 Q29, V30. I have years of math-based science behind me and I used to tutor other sutdents in English when I was in school. I don't know what to do. I don't know what's happening. it just seems like a recurring nightmare. i really need advice, it's too late to apply to more grad schools and I'm thinking of giving up. I can't afford to waste how much more money on an exam that I do well in every single time except for the day of the exam.

It sounds like you were well prepared for your test. Do you think that it was stress that weakened your performance? If you find yourself unusually nervous or distracted during tests, then stress management techniques may be the best thing you could do to perform well on your next GMAT sitting.
