CGPA, or SGPA (Semester Grade Point Average) in Jadavpur University is estimated using several weighted means. Every course of the institute has credit points equal to the respective weights. The SGPA is equal to [summation(f *x)/summation(f)], where “f” denotes credit points, while “x” denotes the absolute grade point in a subject.
The summation, in a way, is supposed to be taken over in the courses per semester.
Here is how the administration signifies the absolute grade points,
Unlike the grading system followed in IITs, Jadavpur University typically follows an absolute grading system. NITs, quite similarly, use the highest grade point as 85–90, while the second highest is 75–85. Thus, the GPA would supposedly be less, as opposed to either NITs or IITs. For example, a 9 pointer is supposed to gain a percentage between the range of 75 to 85. But, in JU, a percentage of 78% will be a close GPA of around 8.3.
