I am in my second semester at Columbia University doing some Post-Bacc work in preperation for Grad School. I have worked really hard this semester, but the chance for a grade of a C looms in one of my classes. I am taking 400 level courses-- in my area of interest, but I did not take a few of the prerequisite-- which has put me behind. I have had to sweat for those possible C's. Should I take the classes Pass/Fail or just take the C letter grade? Please advise. Thank you for your input.
