Course outcome (Course Skill Set)
At the end of the course the student will be able to :
Assessment Details (both CIE and SEE)
CIE for the theory component of the IPCC
Two Tests each of 20 Marks (duration 01 hour)
CIE for the practical component of IPCC
SEE for IPCC
Theory SEE will be conducted by University as per the scheduled timetable, with common question papers for the course (duration 03 hours)
1. The question paper will have ten questions. Each question is set for 20 marks.
2. 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.
3. The students have to answer 5 full questions, selecting one full question from each module.
4. Marks scored shall be proportionally scaled down to 50 Marks.
The theory portion of the IPCC shall be for both CIE and SEE, whereas the practical portion will have a CIE component only. Questions mentioned in the SEE paper shall include questions from the practical component).
