Apply anyway. Most applicants have at least one required pre-requisite course in progress at the time of application. And it really isn't a big deal to us. We only worry if you have a lot of pre-requisites outstanding, because then it can be hard to evaluate your transcript.
You can even be admitted with a pre-requisite, or two or three, in progress. But here's the deal- your admissions is then conditional upon successful completion of the required course (and by successful, I mean a letter grade of "C" or higher). And the course has to be (succesfully) completed by August 1, 2012, in order to actually start classes in the Fall.
So in a nutshell:
- Apply early in our rolling admissions process, even if pre-requisites are in progress.
- Get a minimum of a "C" in all remaining pre-req classes.
- Make sure all in-progress or planned pre-req's will be complete (as in, class over) by August 1.
