Hello there Brent! I too am a Physics major
I would definitely suggest taking chemistry over again if you didn't get it down pat. I am also very interested in acoustics and architecture. The way I see it, you can still learn tons about acoustics by reading. I am interested in many different things in this world....I will study and learn about them all eventually. As far as what you should major in, that it your decision. What would you enjoy doing every day for the rest of your life lol?? The other things you like can be "side studies" what I like to call things or ideas I explore outside of school and work.
