I did not do as well as I had hoped on the GRE. Should I retake it?

It depends. While applications are looked at holistically and other factors will contribute toward our admission decision beside the GRE component, GRE and GPA scores are criteria weighed in your application, so performing the best you can on this test is important. If you do retake it, note that official GRE and TOEFL scores are not self-reported.  You must have official documents/scores sent directly to the Office of Admissions. (See admissions for details).
