I took math 1910, but ended up dropping because although I understood the material, I didn’t prepare well enough for the prelims. I’m planning on taking 1910 again in the spring semester, but would it be bad if I took it at the same time as math 1920? In 1910 I got up to divergence/convergence before I dropped. Also, I’m a physics major in A&S and I’m taking physics 1116 in the spring.
I don’t think that’s possible since 1910 is a prerequisite for 1920, but find out from your advisor or someone in the math department to make sure.
