After taking an impossible ochem exam today that I know I failed, it looks like I'm going to end up with a C in the class. So, I'm trying to decide right now if I should even bother taking the second semester. I'm not a natural science major, so I'm not required to take it. Two quick questions: First, how damaging is a C in one of the prerequisite science courses, and how much of the second semester of ochem directly relates to the first semester? In other words, would it even be possible to get an A or high B in the second half after getting a bad grade in the first semester of the course? Thanks for any advice.
