According to the 2003-2004 MSAR (Table 3-A on p. 12 for those who care), only 23 out of 119 US med schools require any calc. Also, you can still apply to a school that does require it even if you haven't taken calc, and if accepted you would just need to take it before matriculating (I know several people who have done this with various reqs). If it's not required for your major and you don't want to take it, my vote is don't bother- take another class (philosophy, english, whatever) that interests you instead, and make the most of your undergrad years. I dislike math in general and took statistics instead of calc, which I found to be more interesting and useful in my everyday life. I have done fine in my pre-med classes, and I don't think not taking calc has substantially affected my understanding of physics or other subjects, although maybe I just don't know what I'm missing. Anyway, take calc if you want to, but if you don't (and it doesn't sound like you do), don't feel like you have to for med school, as it probably won't matter to the schools you apply at (over 80% have no calc requirement).
