Question paper
pattern:
The question paper will have ten questions. Each question
is set for 20 marks.
There will be 2 questions from each module. Each of the
two questions under a module (with a maximum of 3 sub-questions), should have a mix of topics under that module.
The students have to answer 5 full questions, selecting one
full question from each module.
