看到有学校(CU Boulder)通知免除 2021 fall grad school 申请的 GRE 要求了

In an effort to safeguard educational equity during the ongoing COVID-19 pandemic, we have temporarily adopted a test-optional policy for the GRE requirement. This policy is effective for Fall 2021 applicants.

We recognize that testing centers, schools and universities have been suspended or disrupted, which can make applying to graduate school more difficult to navigate than usual. Your admission decision will not be negatively impacted if you do not submit a GRE score this year. We hope this temporary test-optional policy alleviates some of the stress associated with applying.

好像偶尔确实有一些学校免除就要而已，但是不知道他们招生标准会不会更严什么的？
