Credit hour of the course times the grade value divided by credit hour 👉example:- if the course is Database and has 4 credit hour and you got grade value B which is 3/4 then (4*3)/4=3 for more than one course you will have to add them 👉example:- assume you got ✅ A for Course 1 with cridit hour 3 ✅ B for Course 2 with cridit hour 4 ✅ B- for Course 3 with credit hour 2 ✅ C for course 4 with credit hour 3 then if A = 4, B = 3, B- =2.65, C = 2 (4*3)+(3*4)+(2.65*2)+(2*3) / 3+4+2+3 equals 35.3 / 12 = 2.941 done.
