Thanks and congrats on getting into all those schools!
I'm in 11th grade, the first thing the really grabbed my attention was actually astrophysics, but now I've also picked up an interest in nuclear and high energy physics.To be honest it all seems so interesting, I probably won't get to get to specific into a field until well into college.
Thanks for the link to the textbook, I'd been thinking of getting my self prepared for the concepts in higher-maths but didn't know of any resources, I'll definitely be getting good use out of it.
Good luck in your studies!
Thanks, I'm really happy that I got into a good school. I expected much worse lol. Physics is broader than most people think. UCSD, for one, offers an Astrophysics, Biophysics, Computational Physics, Material Physics, and Earth Sciences specialization in their degree. As for UCSB, I believe they only offer a Physics degree with an optional minor in Earth and Planetary Sciences. Check the course catalog to see if they have classes in the things you might be interested in. You may go from Applied Physics to Biophysics to Particle Physics and back to Applied Physics by the time you finish your G.E, so make sure your school will allow for that.
Remember, no matter how hard it gets, the people next to you are struggling just as much as you. Math and Physics are challenging, but rewarding majors. It will take a lot of studying, but if it's your passion, it's worth it. Physics
