I think that ALL schools should waive the GRE this cycle.
First, the GRE is expensive. Many people don't have extra money to spend during this time.
Also, many people choose to do GRE prep courses. What is the quality of the prep courses if they are online? How many people can learn from an online course?
Taking the GRE at home simply doesn't always work. Dogs bark. Kids walk into the room. Home WiFi may not be great.
Next, people are confined to their homes. Some people don't have adequate study spaces in their homes. It's not safe to be at a public library right now to study.
Additionally, people have so much extra stress during this time. So many people have lost loved ones. It's a scary time.
Also, people have to juggle a lot right now. Some people have to take additional jobs, have to move, etc. to make ends meet. They simply don't have time to study for a big exam like the GRE.
Lastly (for the points that I can think of) a lot of applicants have had COVID themselves! Some people's COVID cases aren't mild and lasts months. If someone decided to apply in October, what if they get COVID in November and the application is due in January? How can that person study and take the GRE in time?
