I have one more semester left in my bachelors degree in International Relations. I would like to do a 180 and continue my education in Physics after I graduate. A bit of background: I have always been interested in astrophysics and have studied it independently for years. Even though it was my plan to study it in college, I shied away from the sciences due to poor performance in math during high school. I just recently took a math class and did very well. I am more confident now that I could get through higher math in order to study astrophysics. None of my undergrad coursework will apply towards a physics degree. Do I have to redo my whole bachelors degree in order to pursue grad school in physics? I'm really not too thrilled about that possibly being my only option. I am mostly concerned about time and also that there's little to no financial assistance for a second bachelors. Are there any other options? Can I take "catch-up" courses at a community college in order to qualify for a grad program? I basically want to know what the bottom line will be for me work-wise and time-wise if I wish to pursue this. Additionally, recommendations for good academics institutions in California, preferably Northern, would be helpful.
