I'm applying for Fall 2013 to biostatistics PhD programs. I go my GRE results back... and they're not so great. I got: 159V, 158Q, 3.5AW. I'm a math major, so I feel like I should've gotten much higher on Q, and I have no idea why I got so low on AW- I actually though I did fairly well. Would it be worth it to retake it? If I did retake, the earliest I would be able to is Nov. 9. Would this be soon enough for December deadlines?
