I worked until the 2nd week of August for the extra cash and for health insurance reasons (so I'd be covered until student insurance kicked in). Then I had a little over a week to visit with friends, pack all my stuff, and a week in Champaign before classes started to unpack and settle in. Give yourself enough time to be destressed when you start classes. 🙂 Some people moved in the day before classes started, and they were a little crazed.
The hardest for me was anatomy, because I only once had a practical exam and never any anatomy. The terminology is the trickiest to figure out initially, then things will start falling in place. I looked over an anatomy text before starting so I was familiar with some terms (cranial, caudal, dorsal, ventral, etc.) before beginning. It would have helped to also know descriptive terms like tubercle, fossa, etc. If you want a latin list, I have one I can e-mail you. But don't review too much. 🙂
The fear of falling behind will probably keep you motivated... it did for me! If you can set aside a couple hours each night to go over what was covered and use the weekends to catch up with stuff you didn't get to, then you'll be fine. Of course I still end up cramming for exams (it's simply amazing how much I learn the night before the exam!) but being aware of what subjects are my weak points and what books are helpful to read (sometimes books not assigned are better, talk to *many* upperclassmen and find out what worked for them), as well as having old exams to see what the professor thinks is important will help a lot. A lot of people study in groups, too... don't be afraid to bounce around to different groups to find someone you are compatible with.
Your brain will figure it out. 🙂 And remember... if you keep throwing **** against the wall, some of it is bound to stick!
