These schools are waiving GRE and GMAT for 2020 due to covid19:

-University of Southern Mississippi
-Bowling Green State University
-The Uni of Texas at San Antonio
-The University of Alabama
-William Carey University

Application is still ongoing.

So far a lot of Nigerians have gained admissions to various American Universities following this waiver. You can Google to confirm and don't say you weren't told.

I have attached a photo of additional schools offering this waivers at this time.

Good luck.
