To qualify the course a student is required to secure a minimum of 45% marks in aggregate
including the semester-end examination and teachers’ continuous evaluation. (i.e. both
internal and external).
A candidate who secures less than 45% of marks in a course shall be deemed to have failed in
that course. The student should have at least 50% marks in aggregate to clear the semester. In
case a student has more than 45% in each course, but less than 50% overall in a semester,
he/she shall re-appear in courses where the marks are less than 50% to achieve the required
Diploma (Mechanical ) Syllabus Applicable w.e.f. Academic Session 2011-12 (22022012) Page 3 of 128
aggregate percentage (of 50%) in the semester. It is compulsory for the student to appear in
external examination to clear the course.
Question paper structure
1. The question paper shall consist of eight questions. Out of which first question shall
be of short answer type (not exceeding 50 words) and will be compulsory. Question
No. 1 shall contain 8 parts representing all units of the syllabus and students shall
have to answer any five (weightage 3 marks each).
2. Out of the remaining seven questions, student shall be required to attempt any five
questions. There will be minimum one and maximum two questions from each unit of
the syllabus. The weightage of Question No. 2 to 8 shall be 9 marks each.
