CBSE Class 12 Practical Exam 2022 (Term 2): How To Score Good Marks In Biology?
CBSE Class 12 practical exams hold marks that are added to the theory marks of the students to generate their final scores in the particular subject. The students must thus not take their practical exams lightly.
Students must prepare their lab manuals and revise their diagrams specifically because many times the external examiners ask them to draw diagrams in the Viva Voice.
Do not try to mug up the experiments. You must just know the process and since the biology experiments are about observations, students must try to demonstrate what they can see, says the retired biology teacher of Kendriya Vidyalaya, Lucknow.
The students take biology practicals very lightly at times and tend to score the lowest in them. It is not easy to remember the biological names of the many animals and plants which is where the students falter.
Practice mounting experiments one time before the actual practical day so that you know the process of making slides. It is quite a delicate process where many students fail. Lastly, study your lab manual well and maintain it before the actual exam day so that the external examiner cannot reprimand you for that.
