The ACS Laboratory Practical Examinations are conducted according to the university norms prescribed for basic engineering practical hours. In English laboratory classes, continuous assessment is carried out during the year for 25 points in the sessions and 50 points in the final exam. Out of 25 points, 15 points are awarded for daily work and 10 points are awarded by performing internal laboratory tests.
The final exam will be conducted by the relevant teacher by inviting the external examiner from outside. In the event of the unavailability of the External Examiner, another teacher from the same department may act as the External Examiner.
