SEMESTER EXAMINATION PATTERN
The Laboratory examination is to be conducted for Group A & Group B, allotting 90
minutes for each group, with a break of 15 minutes. Both the examinations are to be
taken together in sequence, either in the FN session or in the AN session. The
maximum marks for Group A and Group B lab examinations will be 50 each, totaling
100 for the Lab course. The candidates shall answer either I or II under Group A and
either III or IV under Group B, based on lots.
