13) EVALUATION PLAN:

1. The course will be evaluated in two components: Continuous evaluation and End-semester tests. The weightage for the two components is as follows:

Continuous Evaluation: 30 Marks, End- Term Exam: 20 Marks, Total =50 marks

2. Continuous evaluation will include the following:

a) After 2, 4 and 7 th experiments, the ONLINE quiz Test-1, 2 and 3 will be conducted each for 10 marks respectively, Time: 10 Minutes.

b) Total weightage for quiz tests is (10 + 10 + 10 = 30) marks.

c) End term examination will be conducted once all the experiments were demonstrated.

d) End Sem exam (ONLINE MODE) will be conducted for 20 marks, Time: 20 minutes. e) Total weightage for all tests is (30 + 20 =50) marks.

f) Quiz Tests & End Sem. Examination will be the common tests for all the sections (S1 – S14).

3. Total weightage of 50 marks will be scaled up to 100 marks.
