- Already have your end term score?/ 100
Formula: T = max(0.6F + 0.3 max(Qz1, Qz2), 0.45F + 0.25Qz1 + 0.3Qz2)
To sit the end term: average of your best 5 of the first 7 weekly assignments at least 40, and at least one quiz attended.
Weekly assignments carry no weight in T this term, but about 10 marks of quiz and end-term questions come from them.
From the January 2026 Data Science grading document. Check your own term's grading document on the student portal.
How your IITM BS grade is worked out
Every course turns your scores into a total course score, T, out of 100, using the formula in that term's grading document. Many courses take the better of two ways of combining your quizzes with the end term. The calculator shows the exact formula for the course you pick.
You pass a course when T is 40 or more and you meet any extra condition the course sets, such as a minimum OPPE score.
| Total course score (T) | Grade | Grade points |
|---|---|---|
| 90 and above | S | 10 |
| 80 to below 90 | A | 9 |
| 70 to below 80 | B | 8 |
| 60 to below 70 | C | 7 |
| 50 to below 60 | D | 6 |
| 40 to below 50 | E | 4 |
| Below 40 | U (fail) | 0 |
Bonus marks
Some courses add bonus marks for extra activities or programming assignments. They count only once you have passed, so they can lift your grade but cannot get you a pass. T never goes above 100.
Before the end term
To sit the end term you must first be eligible, usually with an average of at least 40 in your best weekly assignments and at least one quiz attended. Each course's rule is shown under the calculator.
Which grading document the formulas come from
The formulas come from the January 2026 grading documents for Data Science and Electronic Systems, the latest versions published openly. IIT Madras publishes a new grading document every term and sometimes changes a course's weights, so check your own term's document on the student portal before relying on a result.
