Physics Major

Alright, I'm at the point where I need to be finding a college soon. Problem is, I'm not sure what classes I really need to be looking for. I'm interested in theoretical physics, specifically cosmology, but I have no idea what classes are typically associated with this. My best guess would be, obviously, cosmology, as well as relativity....but no two colleges seem to offer the same classes. Any help would be greatly appreciated as I'm utterly lost here.

Astrophysics/math double major here.

If you want to do the really cool stuff, you gotta work up from the bottom. Major in physics/astrophysics at the least, then go to grad school for these subjects. Do well in your math courses and your basic physics courses, no matter how frivolous they may seem at the time. You may never have to know how a refrigerator works ever again, but you're not there to REALLY learn physics. You're there to learn a thought process, a way to examine the details and solve a problem using math and some basic axioms.

You should look into schools, specifically universities with strong science backgrounds. This way, when you've been there a year or two, you have a shot at an internship with a professor of some kind, or a lab tech job of sorts. Believe it or not, some schools are actually eliminating their Physics major options because too few people take that route nowadays. So MAKE SURE the school you're looking at actually has a major for physics. You don't need to go to Harvard to become a good scientist. But going to a school with a good science background can make the difference.

That's my 2 cents. Worry about grad school later, it'll clear up.
