For some graduate schools, they are no longer requiring the math GRE subject nor the regular GRE due to the pandemic. On UC Berkeley's admissions site, for example, they write that
Is the General GRE exam or Mathematics Subject GRE exam required?
Due to the COVID-19 pandemic, we plan to make the GRE exams optional for the Fall 2022 graduate admissions application. You may still submit GRE scores; however, an absence of GRE scores will not negatively impact your application.
Taking this statement literally, it seems like there should be no reason to take any GRE examination (at least for Berkeley, and I've found similar statements for other schools). But if that's the case, why do they still accept it? I was wondering if anyone could shed some light on this. Thanks!
