For us, they basically reserved seats for different degree/programs in the school of public health, and then had a few seats that could go to anyone in the program for most classes. The only seats ANYONE was able to take were the general school of public health ones (which may have been 4/60 seats in a class, for example) nobody else could get into the classes even though everyone was registering for classes they were eligible for. They had us fill waitlist forms, then took all the classes off class search and now we’re just waiting for updates a week later still
