B.Sc. (Pass Course) Part-III
The number of paper's and the maximum marks for each paper together with the minimum marks required for a pass are shown against each subject separately. It will be necessary for a candidate to pass in the theory part as well as the practical part of a subject/paper. Wherever prescribed separately. Classification of successfulcandidates shall be as follows :First Division 60% of the aggregate marks prescribed at (a) Part first Second Division 48%Examination excluding those obtained in the compulsory subject (b) Part Second Examination (c)
Part Third Examination taken together.
All the rest will be declared to have passed the Examination. If they obtain a minimum pass marks in each subject viz 36% No division shall be awarded at the Part First and Part Second Examinations:
