ED will still be binding (to the extent it is now). FA offers are likely to be delayed for ED which will delay the commitment date, likely beyond RD deadlines at many schools.
What this means is that students who apply ED and need aid are going to have to get RD apps in next year if they dont have their ED FA package by early December because many students need to do paperwork with their GC office for every school they apply to, and obviously HSs tend to not be open during the first week of Jan, when many RD deadlines occur.
I am on a number of list servs/FB pages with college enrollment peeps and they haven’t really started sorting thru these issues yet.
