So next semester I am studying one section of the Philosophy of Physics at Oxford. This is paid for through my college; thus I can only take 9-12 hours (I am going the third term which doesn't start until late April). I am already a little behind because I had trouble deciding and have three majors (Philosophy, Physics, and Mathematics). Thus, my question is, what should I take next semester. My choices are: One philosophy (to finish my major), then my choice of dynamics, optics, electronics, Calculus III, complex analysis, ordinary differential, and linear algebra. I can only take 2 or 3 of these classes (minus philosophy) so I am trying to decide which are the most important. Input?
