I'm a sophomore undergraduate biophysics + math double major at a T10. After this semester my GPA is going to be 3.79 with a strong upward trend from freshman fall to sophomore fall (I had mandatory pass/fail freshman spring). Some of my lowest grades in college have come in my math classes - a B in calculus 3 freshman fall, an A- in linear algebra freshman summer, and an A- in differential equations sophomore fall. I'm wondering, is it even worth keeping the math major at this point? I'm really interested in math for my own intellectual enjoyment + a sneaking sense that mathematical training will be really helpful in my future research career. I just don't want to sabotage my BCPM GPA, which right now is about 3.81.
