evaluation of 50 marks. A candidate has to secure a minimum of
50% of marks to be declared successful.
5.4
A candidate shall be deemed to have secured the minimum
academic requirement in a subject if he secures a minimum of
40% of marks in the End semester Examination and a minimum
aggregate of 50% of the total marks in the End Semester
Examination and Internal Evaluation taken together.
