I got a guaranteed slot in a university that offers a physics program but I'm doubtful if that is the right choice. I could take this physics program or I could maybe move to another city and study astronomy there. I'm interested in particle physics, mechanics, astrophysics and electromagnetism, all of these seems to favor a undergraduate program in physics. What should I major in? Does it even matter which one I pick? Always wanted to be an astronomer, problem is it's quite expensive having to relocate to another city as opposed to studying in my home, and I already have a guaranteed slot so that is good. Any thoughts? I could you give the program courses if you want to but it's in Swedish. I did study the physics program but dropped out due to medical reasons, so I have the chance to return now in fall, that might give me a huge advantage because I know what to expect, problem is I will be 20 and feel older than others.
