Hi all, I just took the GRE, and I got 163V 158Q and since I would like to enroll in a CS PhD program, i am quite disappointed about my quant. I feel I have an overall kind of strong profile, with a GPA of 3,8/4 (Major 3,95/4), good letters of recommendations, (I don't have publications yet, but I have two presentations and my advisor wants to publish my thesis in the next months, better than nothing I guess...), and a 113/120 in TOEFL. I'm wondering if my GRE score is crushing my application, I wanted to try to go for caltech (and that seems to be impossible with this score) and Northwestern. Should i go for a desperate last try in December?
