Some schools have A's, B's, and then F's starting at 79. I have heard of other programs that do the same thing as yours calling F's in the 70's. The program I just left, you could not continue past a C+ at 77, so that 76 or below might as well as have been F to fail out. It is frustrating but they have to set the standard somewhere for minimum standards of achievement, it is just at a higher level/standard.

Wishing you all the best with the program!!! Hang in there!!!
