Ok here is my situation. I recieved an AAS in automotive science out of high school and have been taking classes ever since part time (about 7 years) at a community college. About a year and a half ago I attended a private college and first semester I took Bio I, Chem I, Phys I, and Prealgebra. Second I took Bio II, Chem II, and Phys II. Other than the math, I basically got all C's. Had to work because I had a daughter and my wife was pregnant. Then we had the second and my wife got pregnant again so I moved back to the community college. Not including these C's I have 121 credits with a 3.81 GPA. So if I get As and Bs the rest of college I should maintain that. I plan to move back to the four year while majoring in a science (either biology or biochem). If I do well in these, would it help offset my C's. My question is should I retake none, some, or all of these prereq classes or just move on, bust nuts, and do well on the rest? If i don't retake these, they will be the only Cs on my transcript. I really appreciate all the help.
