I am a senior in college, and will be graduating in May. I am a BIO major, and the only pre med requirement I have left to finish is Physics and one semester of english. My GPA is 2.86. When I graduate, my GPA is still low, should I take post bacc classes to raise my GPA or should I go straight to a masters program? Is a master's nessasary for admission? I don't want to spend alot of money on a masters for the purpose of admission. Can I be admitted if my post bacc grades are excellent?
