Please help anyone accepted Holy Family U

Hello all. I just finished my final in microbiology and unfortunately it looks like I may get a C which would be my second C in prereqs. I have no problem taking this class over but according to the director of Holy Family program even with meeting the GPA requirements I would have no chance of being accepted into the program. Has there not been anyone ever in the history of the program thats had more than one C?! The thing is I don’t mind taking the class over but he says I cannot do that, I’m really not sure why. I never took any other course over. Please someone help with options. I cannot go to any big name school bc I don’t have the money. Please!
