As we enter the final and most crucial stage of the CBSE Class 12 Boards, it becomes very important that we follow certain practices to ensure maximum performance in the exams. Since last year, the format of the biology paper has changed. The number of sections has increased and the nature of questions has also changed. The number of application-based questions has increased and direct questions has decreased.

Paper will have 5 sections. Section A will have 5 questions of one mark each; section B will have 5 questions of 2 marks each; section C, 12 questions of 3 marks each; Section D, 1 question of four marks and Section E, 3 questions of 5 marks each.

Usually section A and E have direct questions so going through the paper from section E to A (5 marks to 1 mark) helps. Section B and C are application-based sections. Although this article does not in any way state that this is the only way to write the paper, all suggestions are meant to just help students and ensure they have a plan in place for the paper.

Section C is the trickiest part of the paper and carries maximum marks (12 multiplied by 3=36 marks). This means that out of a total of 70 marks, the weightage of 3 marks is more than 50%.

Time management is really very important if you want a score of more than 95 in the paper. Fifteen (15) minutes are given for reading the paper. It should be utilised well. Read the question paper slowly and carefully. While attempting the paper, give 10 minutes to section A, 20 minutes for section B, 60 minutes for section C, 15 minutes for section D and 60 minutes for section E. Use the last 15 minutes to revise what you have written. It is important to support your answers with flow charts, and neat, labelled diagrams wherever possible. In order to help the examiner to quickly identify that you have written all relevant points, please underline the important terms and words.

Unit II of the syllabus has the maximum weightage (18 marks). Revise it thoroughly. Read your NCERT book carefully. Ecology will have largely application-based questions. You should be very thorough with graphs and diagrams of this section. Tables given in Unit III are also very important. Unit I will have comparatively direct questions. Unit IV is the most technical part. Be very clear with the concepts and keywords. Please underline keywords with the help of pencil. Practice attempting full length papers in the month of February and solve at least 10 sample papers including Board papers of the last five years. It will help you immensely.

All the Best!!
