Elaine,
As you so accurately point out, "test scores are not everything." SO why not take it further? Neither are AP exams or SAT IIs. THe Uni curriculum is tough, and while it may not be exactly "AP," I think if you have to endure an added load of study to feel ready for it, the test is not worth it. In the end, what does it gain you other than -- possibly -- a bit of college credit?

Thanks for a bit of clear thinking.
