Credits are derived from weekly contact hours over a semester. Under the common Indian convention, one hour of lecture or tutorial per week is one credit, while two hours of practical or laboratory work per week is one credit. Your university’s regulations set the actual ratio.
Ratios vary between universities and between UGC and AICTE frameworks. Check your own regulations before using a number in a scheme document.
This arithmetic comes up whenever a college designs or revises a programme, and getting it wrong means a scheme that does not add to the required total credits — usually discovered after it has been approved.
Indian scheme documents usually express a course as L-T-P: lecture, tutorial and practical hours per week. The credit value follows from those under the applicable ratio.
| Course (L-T-P) | Weekly hours | Credits (1:1:0.5) |
|---|---|---|
| 3-1-0 | 4 | 4 |
| 3-0-2 | 5 | 4 |
| 2-0-4 | 6 | 4 |
| 0-0-6 | 6 | 3 |
Phrased the way they arrive, answered so each one stands on its own.
Commonly one weekly hour of lecture or tutorial, or two weekly hours of practical work, across a semester. Ratios differ between universities and between UGC and AICTE frameworks, so check your own regulations.
The convention assumes lecture hours carry more expected outside-class work per contact hour than laboratory time does. Whether that reflects reality is debated; it is nonetheless what most regulations specify.
