It's interesting but it's only 14% that separates C+ from A in our school and that is often just an extra half day to finish that last pass over material. Often you just don't have that extra half a day
And yet for some it seems like an abyss separating C students from A students. It's amazing how close it is. However, threads like this are created every year and numerous students are living in despair and stress because of it. I think pass/fail grade system has to be implemented in every school imho
