Neither all can score high marks in the
final exams nor anyone wants to score low marks in the exams. Thankfully previous year question papers can help the students to well in the exams. Solving previous year question papers is important for students.  It would let him get enough practice and be the master of the subject. So we should practice previous year questions. In this purpose, I have given here microbiology questions for BSc in Botany students.  I hope,It will be helpful  for the student of Department of Botany.
