Edit: As in, the admissions committee would rather see you put your time in taking an extra relevant class or doing something else to improve other areas of your application than improving GRE score by a couple points
I took the GRE and got 80% Q and V. I'm applying for top 20 PhD bioengineering programs.
I heard from a professor that after you get a GRE quant or verbal score surpassing the 80th percentile, the admissions commission does not care as much. True or false?
