@Greymeer --depends on the school. I would think a lot of them will have a required course sequence that will make it a four year gig. You can start at Pitt with Calc 3, Physics 2 (having used AP credits for Calc 1 and 2 and Chem 1) but you still have to take first year Engineering Analysis 1 and then Engineering Analysis 2. You also have to take two semesters of Freshman engineering seminar. Heck you could start with 100 credits and you are still going to have to take those two classes in order before being allowed to move to sophomore level engineering. I would expect most schools are like that these days.
