Is there a minimum acceptable score for GRE?
If you get a percentile ranking of 80%, for example, it means that you scored more highly than 80% of your peers, while 20% of your fellow test-takers scored as well or better than you.
There is no single minimum GMAT score for MBA programs, and most schools don’t have a hard GMAT cutoff. However, if you’re looking at top 20 programs it will be almost impossible to get in without at least a 650 (and in many cases that will still be too low)
