Yes. If you are applying to a program where GRE scores are optional, and you choose to self-report your GRE scores in the application, you will be required to also submit official test results for verification purposes. Please be sure to submit your official scores before they expire, since you will not be able to submit them upon expiration and you may be required to re-test. If you chose not to submit GRE scores for a program where GRE scores are optional, official scores will not be required.
