Calculation of SPI and CPI

Suppose in a given semester a student has taken four courses having credits C1, C2, C3 and C4 and grade points in those courses are G1, G2, G3 and G4 respectively. Then,

SPI = (C1 x G1 + C2 x G2 + C3 x G3 + C4 x G4) / (C1 + C2 + C3 + C4) CPI = (SPI1 x Credits in semester1 + SPI2 x Credits in semester2 + ...) / (Total credits)

For example, if in a given semester a student has taken four courses having credits 6, 6, 8, and 6 and grade points in those courses are 10, 9, 8, 6 respectively. Then, SPI = (6 x 10 + 6 x 9 + 8 x 8 + 8 x 6) / (6 + 6 + 8 + 6) = 7.62

If the student has an SPI of 7.62 in the 1st semester worth (say) 32 credits and 8.2 in the next semester worth 36 credits, CPI (at the end of 2nd semester) = (7.62 x 32 + 8.2 x 36) / (32 + 36) = 7.93

Do note that all semesters have more or less equal credit weightage, so it is important to do well throughout, and not just in final exams, in order to maintain a good CPI.

Grading

The system of grading here, in most courses, is relative. The highest grade (worth 10 points) is set according to the highest score obtained in the class, and proportionately, grades are allotted to all students. Grading, in integral values out of 10 is done based on the student’s performance throughout the semester and goes from 10 to 4 (AA-10, AB-9, BB-8, BC-7, CC-6, CD-5, DD-4).
