Question

Arun Bajaj · Accepted Answer

IIT-Madras uses a relative grading system that varies by professor, department, and course. Grades range from S to U, with corresponding marks. Here’s a quick breakdown:

Grade	Marks Secured
S	10
A	9
B	8
C	7
D	6
E	4
U	0
W	0

U : Fail due to low marks.
W : Fail due to attendance (IIT-Madras requires 85%, but it can be lenient).

To calculate grades, the average marks (Av) and Standard Deviation (SD) are used:

S Grade : Av + 3SD
A Grade : Av + 2SD
B Grade : Av + SD
C Grade : Av
D Grade : Av - SD

CGPA is calculated as a weighted average based on course credits.
