My program was only 1 year, but this was back in 2006, so not sure how much things have changed.
It started in the summer. I took gen chem 1 and 2. In the fall I took Bio (not 101 because I had already taken 101, so I took a little more advanced class), Organic Chem 1 and Physics 1...all with labs. Then, in the spring I took Organic 2, Physics 2 and then I was planning to take Biochem, but opted to work more at my part time job.
It wasn't too bad.
