UPDATE:
I’ve decided to take Bio 1, Chem 1, Calc 2, a second-tier astronomy class (because I took Astro 1 already), and Intro to Gender/Women’s Studies. I’m sure I can handle all of that since Physics 1 is gone. I decided to accept that Physics 1 can’t happen this semester and drop it, and that I can always take Physics 1-2 as a junior and perhaps minor in it. I’m going to stick with my Environmental Science major, and I might do a self-designed Geophysics concentration within that major, which would mean taking physics as a junior, as I said above. I suppose if I still wanted to pursue astrophysics someday, that wouldn’t be impossible in a grad school given this science-oriented undergrad experience. Thanks for all of your tips, guys.
