<p>Well, a lot of people start taking chemistry classes at UNC and realize… wow, this shiz is hard. Really, really hard. So it’s not so much that you want the BA over the BS, it’s that you want to save your sanity and GPA by cutting out some of the chem classes. The Chemistry BA major can actually be a huge life saver. Unless you’re going to major in math or something along those lines, I just don’t see the point of retaking the calculus. 231 and 232 are huge pains, and they’re going to teach you what you need to know calculus wise in your bio and chem classes anyway. I wouldn’t get fussed about the calculus/physics stuff until you have a better idea about potential majors.</p>
