Theory Examination : 1. Question paper will be comprising of total 7 questions, each of 20 marks. 2. Only 5 questions need to be solved. 3. Q. 1 will be compulsory and based on entire syllabus. 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 hours as mentioned in the syllabus. Term Work :

Term work will be in the form of Journal which will consist of minimum ten tutorial assignments covering the entire Portion and a written test paper. The distribution of marks for term work shall be as follows; Laboratory work (Experiments and Journal ) : 10 marks. Test (at least one ) : 10 marks. Attendance (Practical and Thaeory ) : 05 marks. The final certification and acceptance of term work ensures the satisfactory performance of laboratory work and Minimum passing in the term work.
