Hmmm....be prepared b/c calc based physics will be 10 times harder than your current course, well maybe not that much harder. It's a pre-req for most science/math majors. If you can't get past physics how are you going to make it through to med. school? LoL....
Edit: Actually, there are people that find calc based easier, just lik pre-cal is easier for some than calc l. I guess it also depends on your interest and pre-existing knowledge of the subject matter from high school.
