I don't know what kind of schools you are looking into. You said you want to study at some good univeristy. Then even if you are talking about some second tier university, I think you should at least have a combined score of 1200 ( if you want funding from the college). Otherwise, I think you can get into schools with that score. I know this girl who got into the masters program of NYU with a 1050. But she got no funding. All I'm trying to say if you take your GRE in november, the prep time you would get, would not be enough to have a significant increase in your score. I hope it helps :-)
