Question paper pattern:

Examination will be conducted for 100 marks with question paper containing 10 full questions, each of 20 marks.
Each filll question can have a maximum of 4 sub questions.
There will be 2 full questions from each module covering all the topics of the module.
Students will have to answer 5 full questions, selecting one full question from each module.
The total marks will be proportionally reduced to 60 marks as SEE marks is 60.
