NewJerseyMom: To find courser descriptions online, go to
http://www.unc.edu/ugradbulletin/depts/index.html
and then click on the department through which the course is offered. Scroll down (sometimes quite a ways) on the department page and you’ll find course descriptions. It's a bit of a pain, but I've never found them all in one spot -- only department by department.
My OOS daughter did the August CTOPS, had a lot of AP credits, and she was fine with getting good courses. She initially didn't get one that she wanted, but she was online the moment drop-add started (7:00 or 8:00 a.m.!) and added that course and got a better time for another course. She did this at the hotel, in the business center, and there were other UNC OOS August CTOPS kids doing the same thing!
She liked being able to move in early and get settled. We had plenty of time to do the Target and BedBath trips. It worked well.
