If you're not doing too well with University, the first expansion pack of the Sims 2 that is, then IGN has a solution for you. They've published a guide which takes you through the most important parts of the game. New items etc. are briefly introduced, followed by a College 101 which is all about creating and going to college. Some special places at the campus are discussed after that, followed by a few notes you can't miss. If you can't afford the comprehensive Prima guide or just don't want that, this might be a good (free) solution instead. It might not be as big, but it should get you started. Go to the guide for the info.
