* The examiners shall mark the experiment(s) of sections A, B & C and submit the marks to the chairman of the relevant examination committee. The final marks shall be computed by the committee.

** The class teachers of sections A, B & C shall evaluate continuously the Lab. classes out of 15 marks and submit the average marks of Lab. evaluation in sealed envelopes to the Chairman of the relevant examination committee within three weeks from the last Lab. held. The average marks shall be computed by the examination committee.

The total marks of the practical course shall be obtained by adding the marks of section A, B & C. The examination committee shall send a copy of each of the average consolidated marks of practical examination, lab. evaluation, viva-voce examination and class evaluation to the controller of examinations.
