BLUEPRINT OF SYLLABUS STRUCTURE AND

QUESTION PAPER PATTERN

Blue Print of Syllabus Structure

1. Complete syllabus is prescribed in SIX units as Unit 1, Unit 2, etc.

2. In each unit there is one topic under the heading “Self Learning Exercises” (SLE). These are the topics to be learnt by the student on their own under the guidance of the course instructors. Course instructors will inform the students about the depth to which SLE components are to be studied. Thus there will be six topics in the complete syllabus which will carry questions with a weightage of 10% in SEE only. No questions will be asked on SLE components in CIE.

Blue Print of Question Paper

1. Question paper will have SEVEN full questions.

One full question each of 15 marks (Question No 1, 2, 3, 4, 5 and 6) will be set from each unit of the syllabus. Out of these six questions, two questions will have internal choice from the same unit. The unit from which choices are to be given is left to the discretion of the course instructor.

2. Question No 7 will be set for 10 marks only on those topics prescribed as “Self Learning Exercises”.
