which has become a brand name among hundreds of colleges

in the country. Infact, NIE is one of the top ten preferred

colleges where all the seats got filled-up in the first round of

2015 admissions.

The concerted efforts of stake holders at NIE have made it get

autonomous status, prestigious TEQIP-I & II and get

accreditation from National Board of Accreditation, New Delhi.

NIE has been granted permanent affiliation by VTU to all its

courses.

Today NIE has of 7 UG, 13 PG and 5 Post-graduate Diploma

programmes and 13 Centres of Excellence with overall student

strength of over 3500. NIE's journey to excellence, with the

main objective of continuous improvements of administrative

and academic competence, is envisioned through three major

pillars: intellectual infrastructure, courses/services offerings and

institution building.

Our curriculum is designed to develop problem-solving skill in

students and build good academic knowledge.

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.

2. 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.

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