I'm not 100% sure what I want to do after college, but I know I major in physics. I ultimately want to be a college professor. Currently, my top choice is University of Maryland. I'm going into my senior year of HS, and I'm going to have nearly 70 credits going into college. For this reason, I am leaning towards a double major. These are the fields I have been thinking in double majoring in: Astronomy: I have had an interest in black holes, space, etc. since I was a kid. I'm thinking about focusing on this area in grad school. Not sure if there would be any point to the double major though, and I'm not sure how strong Maryland's astronomy dept. is. Math: Seems like it would make go well with physics, math is my strong point but I don't particularly enjoy the lengthy, meticulous problems. Finance or Accounting: Would leave me with many options after undergrad, apparently firms like people with technical backgrounds, and professors are paid well. The physics would help if I went into business, but I doubt the converse is true. Is there anything I'm missing? Do my assumptions seem correct? Are any of these particularly good choices? Any advice is appreciated.
