I have got C grade in 7 subjects and D grade (in last attempt) in remaining two subjects in Section B exams. Got H grades in both Lab and project work. Even then I am not declared pass. Why?

For PASS, you must get B grades in few subjects, to make total GPA equal to 6 or more. Grades of Lab/Project work will not be included in this GPA calculation.
