The Executive Secretary of NUC noted that while some universities used the 6 grade points of 5, 4, 3, 2, 1, 0 for letter grades of A, B, C, D, E, and F respectively, other disciplines, he said, removed the E grade altogether thereby having a grading system with grade points of 5, 4, 3, 2, 0 for letter grades of A, B, C, D, and F respectively. He added that these methods had incontrovertibly introduced two systems of grading within the NUS that had some technical implications on the grading of students.
