What Are The 7 Common Mistakes You Should Avoid In The CBSE Class 12 Biology?

By Sashikanth Sai

The CBSE Class 12 board examinations are taking place with a record number of students attempting it. And students are all set to take the most theoretical subject, Biology, on Mar 27, 2018.

The subject Biology is most loved by all the students because of its concepts. There is a saying for the CBSE Class 12 students that, more than ninety per cent of the job will be done if a student simply mug up the concepts in Biology. Unfortunately, even this subject has become a nightmare to students. This is mainly because students are not able to score 100 in Biology despite the best effort. So where is the problem?


Many students commit some mistakes unknowingly while taking the Biology exam. With careful attention, one can avoid them. Here are the nine most common mistakes you should avoid in the Biology paper.

1. Keeping The NCERT Book Aside

Due to various reasons, students usually travel with the reference books while keeping the NCERT books aside. This is not a good idea because the board examiners will evaluate the papers based on the NCERT. Reading the reference books once in a while is fine, but not always. To be honest, reading the NCERT book cover-to-cover is the key for achieving the full score in the CBSE Biology exam.

2. Not Using The Reading Time Fully

Around fifteen minutes of time is good enough to read the Biology paper in the Class 12. During this time, students should prepare the strategies for answering the questions in the right way. Even the concentrated reading will make you understand the sub-questions in the long questions while minimizing the errors.

3. Writing A Long Paragraph

3. Writing A Long Paragraph

Students should prefer the point-wise presentation rather than writing a huge paragraph. The point-wise answers not only generate interest, but also makes the examiner's job easy. It is even suggested to highlight the important terms in the answer. However, schematic or flow-chart form is advised for long answers.

4. Not Drawing The Diagrams

The Biology subject is popular for diagrammatic illustrations. Be it of 2 marks, 3 marks or 5 marks questions, students should write their answers by providing a diagram whenever required. It is suggested to use pencil only for drawing. However, never forget to label them.

5. Writing More Than Required

The CBSE encourages students to hit the bull's eye rather than the word limit. Only two points should be provided for the two marks question. Writing a lengthy answer than required will only reduce your precious time and energy.

6. Not Going For An Organised Approach

Many students usually jump to another section without completing one section. This activity can irritate the examiner and may lead to improper marking. It is better to avoid this approach.

7. Writing Till The End

A student who lacks in the time management will surely fail to gain the perfect score. Writing the exam to the last minute is a consequence of the time mismanagement. This has to be rectified immediately because one should use the last 5-10 minutes for revision.

While taking the Class 12 Biology exam, students should touch the values and life skills besides mentioning the facts. This is surely a scoring subject in the Class 12 and never compromise on that at this final stage. We wish you good luck!
