#1 how bad does a bad grade hurt assuming all other grades are good. I.E. I am a non trad returning to college, I got a 2.0 in bio back in 1996, but when I returned I got a 4.o in bio. Also, because of my wedding, it looks like my grade in this summer chem 2 will be bad, like a 3.0. How bad does this hurt me? #2 Is a science gpa of 3.29 competitive considering working full time and going to school full time? BTW- I am planning to go D.O.
