I am currently signing up for classes next semester. I am already taking Linear Algebra, Physics 2 + Lab, and a required writing course. As my fourth choice I can either take Astronomy + Lab or Introduction to Probability and Statistics. The pros of statistics are that there is no lab, which tends to be time-consuming. However, the astronomy course seems fun and is required if I choose to be an astrophysics major (vs. just physics), though I'm still not sure that I want to overspecialize during undergraduate since I'm not dead-set on astrophysics. I could also take five courses, but I worry that that would be too much... I tentatively am planning on physics + math and hope to become a theoretical physicist, though lab in college has proven to be a lot more fun that high school labs--data is beautiful! Any advice?
