I'm such an idiot.
Full semester classes start today, so half an hour before I think I'm supposed to go to class, I check my schedule online just to confirm everything (I mainly wanted to know what room I had to go to). My school's calendar app was starting out everything in October, so after backtracking to this month and finding diddly squat, I looked up the class information. They're 8-week fast-track classes that begin October 19th.
Whoops.
Whoops.
