What is C-wall?
1.
Any college course that requires a grade of C or better to move on to a more advance class or to earn a degree. Failure to eran the required C in these classes often results in people either changing majors dropping out of college.
Did you hear that Joe got a C- in College Algebra? Now that he's hit a C-wall, he's going to have to become a theatre major just like us.
