1. Question paper will consist of total 7 questions carrying 20 marks each.
2. Only 5 questions need to be attempted.
3. Q.1 will be compulsory and based on the entire syllabus.
4. Remaining questions will be mixed in nature.
5. In question paper weightage of each module will be proportional to the number of respective lecture hours as mentioned in the syllabus.
Practical & Oral Examination:
Practical examination will be based on one experiment performed from the list of
experiments given in the syllabus and the oral will be based on entire subject. The distribution of the marks shall be as follows,
Practical examination : 25 marks Oral examination : 25 marks Term work:
Term work consists of minimum eight experiments, a written test and industrial visit
report. The distribution of the term work shall be as follows, Laboratory work (Experiments and Journal) :10 marks Test (at least one) :10 marks Attendance (Practical and Theory) :05 marks
The final certification and acceptance of term-work ensures the satisfactory performance of laboratory work and minimum passing in the term-work.
*Oral Examination Based on Object-Oriented Industrial Visit
