I'm currently a junior and a half i guess. i took summer classes and class overloads to get there, but in my rushed, crammed life my GPA has fallen. (it might have something to do with takin org.chem, physics, botany an others in one semester.) My school offers the opportunity to retake classes and replace your grade. I have two C's in org chem and a couple more in other classes. Would it be in my best interest to retake my org chem classes over or should i just focus more on the rest of my classes? How much would those C's in org chem effect me when applying if i didnt retake it?
