Hi all, I am an international student doing my undergraduate degree in the US. I am shooting for PhD program of top 20 schools (I don't have a Master degree yet). I did my GRE twice: first one in August (164Q, 152V, 3.5AW) and second one earlier this month (170Q, 155V, 3.0AW). I was shocked by my new AW score. I thought I did it much better than the first time... So my question is should I request a rescore or retake the GRE? Or my current score is fine (just send the schools both of the scores maybe?). I have a 3.57GPA from the top 30 liberal arts schools (with a strong engineering program). No publication but I will present one of my research projects at the APS conference in Boston this November. What is my chance for top 20? (Since a lot of schools have a 3.5 AW cutoff). I really appreciate all of your opinions!
