My Current Situation: I am currently a second semester sophomore at university going for a double major (BS in Physics and BS in mathematics). I went to college to get a physics degree . The mathematics degree is added on because I love mathematics and due to my strange circumstances had quite a lot of credit hours to fill as a sequentially go through my physics curriculum. To get my beloved BS in Physics, I would have to be here the next 2.5 years (graduate after Spring 2018). However, I only need 1.5 years to graduate with a BS in Mathematics. (graduate in Spring 2017). My question If I were to just get my BS in Mathematics and go to graduate school (just to keep things simple, lets say I go to graduate school at my same university), could I go to graduate school for physics? I have heard that this is true. Would I be able to finish my few classes for my BS in Physics degree while I am in graduate school. (again, assuming I am at the same school, same curriculum). At the end of the day, I came to school to get a BS in physics, not a BS in mathematics. I will do the 2.5 years as I originally planned, but if there is a way to make myself a graduate student earlier, that would certainly help financially and professionally, I imagine. Opinions on this? Thank you.
