This course's certificate rule
Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course. Exam score = 75% of the proctored certification exam score out of 100 Final score = Average assignment score + Exam score Please note that assignments encompass all types (including quizzes, programming tasks, and essay submissions) available in the specific week. YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Credit for your degree
The course page prints 4 credit points, but your own university decides whether and how much it counts — ask your department before the semester starts. How SWAYAM / NPTEL credit transfer works
Shishya never gives answers to graded NPTEL assignments.
