No. It is not too late to apply for 2003 entering class. There is one more exam coming in january and another one in March (i think, check the pcat site) but I suggest that you take the one in january. if you took the mcats, then the pcats should be no problem for you.
however, send in your applications in first so all they will need are your pcat scores. Don't apply to pharm d school just because you can't make it into medical school. Do what you enjoy.
Consider post bac programs for medical school if that is what you want to do.
Good Luck.
