Questions
Which syllabus does this course follow?
It follows the UP State Universities NEP 2020 common minimum syllabus for B.Sc Zoology, Semester 3. Where your own university's syllabus differs, the centre follows your university's syllabus and question pattern.
Is this paper only theory?
This is the theory paper. Its companion Bioinstrumentation Lab covers hands-on use of the same instruments.
Is there a test after the course?
Yes. Unit-wise multiple-choice tests and a final exam paper are included for semester exam practice.
