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 from which choices are 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”.
