PREFACE Dear Students,

From the academic year 2014-15 there is a slight

change in the syllabus structure and question paper pattern.

This change is due to the philosophy of Outcome Based

Education and requirement as per the National Board of

Accreditation (NBA), Government of India, New Delhi.

Sixteen countries including New Zealand, Australia,

Singapore, Russia and India are the signatories of the

Washington Accord, which has come out with the new

process of accreditation. This would enable every institution,

including NIE to attain high standards of technical education

in the respective countries and to create level playing

ground. The outcome based education is one of the

important components of NBA.

NIE is making sincere efforts in meeting the global

standards through new formats of NBA and timely World

Bank-MHRD initiative TEQIP (Technical Education Quality

Improvement Program). Efforts are being made to revise the

syllabi regularly to meet the challenges of the current

technical education.

BLUEPRINT OF SYLLABUS STRUCTURE AND

QUESTION PAPER PATTERN

(to be effective from the odd semester of the academic year 2014-15 for all semester students)

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 in which choice is to be given is left to the

discretion of the course instructor.

3. Question No 7 will be set for 10 marks only on those topics

prescribed as “Self Learning Exercises”.
