Only ‘D’ or higher grade will be counted as credits earned by a student.
A student obtaining ‘F’ grade in any course (theory and practical) will not be awarded degree. Student with ‘F’ grade in any course shall be allowed to improve twice/two times only with the following batches.
5. Assessment and Evaluation
The performance of a student in a given course will be evaluated in the following way:
At the beginning of each academic session, an examination committee is to be constituted for that session by the respective department. The examination committee will have a Chairman, two internal members and an external member. The Chairman of the Examination Committee will act as a course co-coordinator for that session.
It will be as follows:
|
|
Class attendance |
05% |
|
|
In-course assessment |
25% |
|
|
Course final examination |
70% |
