I took the GRE last year and didn't do well: V- 440 (46 percentile), Q- 490 (25 percentile), and W- 3.0 (10 percentile). Now granted I had way too much on my plate at the time: I was taking 20 credits at the time, applying to 5 grad schools, in my senior year, my mom was battling cancer, I was sick with the flu, had been up all night the night before with my daughter who was also sick, etc! It was a horribly stressful time and if I could go back I absolutely wouldn't take on so much. So I took the GRE about 1 year ago, applied to grad schools, and got into all but my #1 choice. I deferred entry to all 3 schools until next Fall so that I will be able to get a G.A. and also so I can reapply to my #1 choice school. In my favor, I have a great essay (several Professors have read it and given me suggestions), 3.9 GPA, and glowing recommendations. I also have direct experience in the field to which I am applying. I believe I have learned a lot about myself and what I really want in a graduate school/program since last applying and I have explained that in my essay. Now my question is: do I retake the GRE? I am certain I can improve my W to at least a 4.0 but am unsure about the Quantitative. I would like to improve my Q to the 40th percentile at least. It would be nice to improve my V to the 50th percentile but the school I am applying to likes to see scores in the 40th percentile and above (although I know someone who had BAD scores and still got in). I am just afraid that I will retake it (spend $130) and barely improve at all. How can I improve my Q significantly? I am not stupid: I have had all A's in my math courses, I just hate standardized tests! I have Kaplan and Barrons GRE prep books. Any other suggestions? Should I get a tutor? Please help!
