General guidelines:
General guidelines:
- All the submissions should be on time. Delayed submission will attract penalty at the rate of 10% per day. After delay of 10 days, no marks will be given to a assignment.
- Plagiarism of any sort (from internet resource or from friends) will be heavily penalised. In case, the case of copy is from other students of the course, both parties will get negative marks equal to double the weightage of assignment/submission. In second instance will be given F.
