I took the GRE few days ago and got Q166, V155. All of my simulations were 169+ in Q (1 incorrect answer) and I really don't know what went wrong. I am planning on applying to top15 math programs in the us including (mit, princeton, stanford, harvard, ucla, berkeley, etc.).
I am confident that I can get a better Q score if I retake the test but I am not sure I want to spend the time and money on it (at least another 3 days including test day).
Do you think I will make the top universities cutoffs? Should I retake? Can this score be the tie-breaker in some cases and lead to me not getting accepted?
