Question Paper
Pattern:
¢ The SEE question paper will be set for 100 marks and the
marks scored by the student will be proportionately reduced to 60.
¢ The question paper will have ten full questions carrying
equal marks. ¢ Each full question carries 20 marks.
¢ There will be two full questions (with a maximum of
three sub questions) from each module.
¢ Each full question will have sub question covering all
the topics under amodule.
The students will
have to answer five full questions, selecting one full question from each
module.
