So I'm a 4th year biology major. I absolutely hate what I have been/am learning but that's another story. Ideally, I'd like to get into the field of math and get a master's/PhD degree but I've only taken up to CalcII - and that was about 3 and a half years ago. I did, however, love the math classes I was taking and I've always felt that it was the right path for me. I really, honestly enjoyed doing math problems and they gave me a joy that I wasn't getting from learning chemistry and biology. Now, like I said, I want to get a masters but I know that there are pre-reqs I need to do. Should I hold up graduation and finish them or do a post-bacc program? I'd like to get into research if I do hold up my graduation and I can also rack up math related LORs as well. My gpa is not so great, too. Again, a story for another time. If I do well in my upper level maths, will this be added to my undergrad gpa? Will grad schools take that into consideration? Help me out!
