So I have Created three grade types: 1st CA (20%), 2CA (20%) and Exam(60%), all summing up to a final score. The final Grade is to be interpreted in this range of grades (75-100 : A, 70-75 : B2, 65-69:B3, 60-64: C4 etc). How do I go about setting this up as a grade scale of the final score?
Please, I need this urgently? thank you
