So, I want attend either college X or Y; I'm using variables because I don't want to expand on the college, et cetera. If I choose to attend college X, I have to take a Computational Physics class to acquire the B.S. in Physics. Unfortunately, college Y does not offer Computational Physics as either a class or major requirement, but it does offer Numerical Analysis. The thread "So You Want to be a Physicist?" mentioned that as an undergraduate, taking either a computational physics or numerical analysis class is eminent. That is why I'm a bit worried about taking one or the other, and stuff. So, could I substitute a Computational Physics class for Numerical Analysis, just in case I end up going into college Y?
