I'm starting class in 3 weeks and need a bit of help deciding which classes to take. I took Gen Bio, Gen Chem, 1 quarter of O Chem and 1 quarter of Physics while doing my UG the first time (12 yrs ago) and got about a C+/B- average in them. I've decided not to retake Gen Chem but just start fresh with O Chem and I have enrolled in Physics and Gen Bio. I'm now debating whether I should drop the Gen Bio and do some UD coursework instead, BioChem and Molecular Bio. The effect on my GPA of retaking any coursework will be minimal even if I get an A+, but I am thinking that UD coursework will look better. Will I be in over my head in UD coursework since it has been 12 yrs since taking Gen Bio?
