Any other experiment based on above syllabus.

Term work:
Term work shall consist of minimum six experiments (at least one experiments on Dynamics), assignments consisting numerical based on above syllabus, at least 3 numerical from each module.

The distribution of marks for term work shall be as follows:
1. Attendance (Theory and Practical) : 05 marks
2. Laboratory work (Experiment/ programs and journal) : 10 marks
3. Assignments : 10 marks

Assessment:
Internal Assessment Test:
Assessment consists of two class tests of 20 marks each. The first class test is to be conducted when approx. 40% syllabus is completed and second class test when additional 35% syllabus is completed. Duration of each test shall be one hour.

End Semester Theory Examination:
1. Question paper will comprise of total 06 questions, each carrying 20 marks.
2. Total 04 questions need to be solved.
3. Question No: 01 will be compulsory and based on entire syllabus wherein sub-questions of
2 to 5 marks will be asked.
4. Remaining questions will be mixed in nature.( e.g. Suppose Q.2 has part (a) from module 3
then part (b) will be from any module other than module 3 )
5. In question paper weightage of each module will be proportional to number of respective
lecture hrs as mentioned in the syllabus.

Oral Examination: Oral examination will be based on entire syllabus
