According to Higher Education Commission guidelines:
1 Theory Credit Hour = 1 class of 50 minutes per week
1 Lab Credit Hour = 3 contact hours per week (3 × 50 minutes)
Semester duration = 16–18 teaching weeks
Given Workload:
15 Credit Hours (Theory)
3 Credit Hours (Lab)
Total = *18 Credit Hours
Weekly Calculation
Theory
15 credit hours = 15 classes per week
(Each class = 50 minutes)
Lab
3 credit hours × 3 contact hours = 9 lab contact hours per week
Total Weekly Contact Periods
15 theory periods
9 lab contact periods
Total = 24 contact periods per week
Semester Calculation
If Semester = 16 Weeks
Theory:
15 × 16 = 240 theory classes
Lab:
9 × 16 = 144 lab contact hours
Total Contact Periods in Semester:
240 + 144 = 384 total teaching periods
If workload is
15 theory + 3 lab (18 credit hours total):
24 teaching periods per week
384 periods (16-week semester)
