Calicut University offers 2 types of exams to compensate for below minimum marks:

1. Improvement Exam

2. Supplementary Exam

If you are referring to an Improvement Exam to increase marks of an exam you have already given then the answer is no.

But if you are referring to the Supplementary Exam to pass an exam you haven’t obtained minimum marks in yet, the answer is yes. There might be some chances for the same.

You cannot apply for an improvement paper if you have obtained your provisional degree certificate. This is because once you receive the provisional certificate it means you have successfully passed the course and no further changes can be made. 

Any more doubts can be further addressed to the University Exam Wing. Just make sure to keep important documents within reach.
