M.Sc Bioresources


M.Sc. Bioresources

Note: The syllabus prescribed for the entrance test has been divided into fifteen units. Each unit carries a Weightage of four marks. Paper setters are required to set four multiple choice type questions with only one correct or most appropriate answer separately for each unit, giving uniform representation to the whole syllabus contained therein.
