Ok but converting an ED application to RD is done, and not against college policy, so the GC couldn’t really do anything about that since it does not need their signature. Only if you’re converting RD to ED 1/2, do you need the GC.
So if a student really didn’t want to attend a college they got in ED, the GC would force them to go? Sounds like the GC is more interested in the school’s reputation than the students.
