Syllabus M.Sc. Prev. Botany
Scheme – Each paper have 9 questions, out of which a student has to attempt 5 questions including the question No.1 witch will be compulsory. The question No.1 will carry 20 marks and will be of several short objective type questions such as multiple choice type, one liner answer type , one word type and fill in the blanks types.
