Well, admission decision by a university is based on many factors. They look at your academics, GRE, TOEFL scores and other activities as well, including your Statement of purpose and other things.

One way to look at schools is to find schools that you are interested in by your major or specialization and then see where you can fit. You can look at the average scores of GRE and TOEFL in the Universities websites to get an idea. Just do some research, you will get some ideas.
