I contacted seven schools that are on my list. It seems to differ by program and some told me about a week and a half ago that they are assessing the criteria as each week passes, or won't make decisions until closer till when applications open up. From the schools I've contacted or seen posted online, pretty much all programs will accept a GRE taken at home and will accept courses and labs that are taken online from Spring and Summer 2020. Criteria for observation hours and LoR differ from program to program right now.
