COURSE EXIT SURVEY (mention the ways in which the feedback about the course shall be assessed)
Feedback from the student after 18thweek :on knowledge gained, subjects relevant to the course, methodology adopted, aspect of improvement. Whether the topics fulfill the course outcome and program outcome.
COURSE POLICY (including compensation assessment to be specified)
Absenteeism in Assessment: Extra chances will be given to the students (on medical or official purpose) not appeared in any assessments 1 - 3 with full syllabus.
ATTENDANCE POLICY (A uniform attendance policy as specified below shall be followed)
At least 75% attendance in each course is mandatory.
A maximum of 10% shall be allowed under On Duty (OD) category.
Students with less than 65% of attendance shall be prevented from writing the final assessment and shall be awarded 'V' grade.
ACADEMIC DISHONESTY & PLAGIARISM
Possessing a mobile phone, carrying bits of paper, talking to other students, copying from others during an assessment will be treated as punishable dishonesty.
Zero mark to be awarded for the offenders. For copying from another student, both students get the same penalty of zero mark.
