Assessment:

Internal Assessment for 20 marks: Consisting Two Compulsory Class Tests First test b ased on

approximately 40% of contents and second test based on remaining contents (approximately 40% but

excluding contents covered in Test I). Duration of each test shall be one hour.

End Semester Examination: Weightage of each module in end semester examinati on will be proportional to

number of respective lecture hours mentioned in the curriculum.

1. Question paper will comprise of total six questions , each carrying 20 marks

2. Question 1 will be compulsory and should cover maxi mum contents of the curriculum

3. Remaining questions will be mixed in nature (for ex ample if Q.2 has part (a) from module 3 then part

(b) will be from any module other than module 3)

4. Only Four questions need to be solved.
