However, to be able to score well in the subject in your Class 12 Biology Board Exam and in any other competitive exams ahead, here are a few simple and easy tips to help you during your preparation as well as your exam:

What to do during your preparation?

  • Make sure you know the syllabus
    The Central Board of Secondary Education (CBSE) often makes changes in the syllabus for Class 12 according to the student’s requirements. So, before you start your preparation, you need to ensure that you have the latest syllabus with all updates if any. If you have the latest syllabus, you will know how much you need to cover in the time you have before your exams begin. Here is the latest syllabus provided by CBSE for Class 12 Biology: 
  • Unit VI – Reproduction (Chapters 2 and 4)
  • Unit VII – Genetics and Evolution (Chapters 5 and 6)
  • Unit VIII – Biology in Human Welfare (Chapters 8 and 10)
  • Unit IX – Biotechnology and its Applications (Chapters 11 and 12)
  • Unit X – Ecology and Environment (Chapters 13 and 15) 
  • Refer to NCERT
    The main source for your preparation should be the ncert biology class 12 pdf book. Firstly, read all the chapters one by one, and be thorough with each and every topic discussed in all the chapters. Then, attempt the NCERT questions provided after every chapter in the book. These questions will help enhance your understanding, provide you a quick revision of everything you read in the chapters, and give you an idea of the questions that can be asked in the exam. NCERT is the main basis for the questions that are given in the Board Exam. Hence, being thorough and having in-depth knowledge about all the concepts and topics will help you answer all questions easily.
  • Make Notes
    A very important part of your preparation should be making notes as you go through chapters. The syllabus contains a lot of things that you will need to remember for your exam, and making notes will help you with that. Once you understand the information and write it down in your language, you will remember it better. This will also ensure that you are not just reading chapters but actually understanding them. The notes you make will make the concepts easier to understand later during your revision. You can keep your notes handy and go through them at any time for a quick revision before your exam.
  • Practice drawing diagrams
    Biology involves a lot of diagrams to explain different processes, objects, and their working. It is certain that there will be questions in the Class 12 Biology Board Exam that will need you to explain terms by drawing diagrams and these usually hold a weightage of 5-6 marks. Practice drawing diagrams, especially if drawing is not your best skill. Ensure your diagrams are clear, understandable, and labelled accurately. If your diagrams are messy, unclear, or not well-labelled, you will lose marks that can be scored very easily.
  • Solve papers
    Students are advised to look for study material like sample papers, mock tests, previous years’ papers, etc. for more practice and revision. Make sure you also have the answer keys to check how you perform. Do note your mistakes and try to understand how to rectify them. Solving question papers will also determine your strong and weak points so that you can work on them accordingly. Observe the questions that are often asked in question papers over the years and prepare well for them. Notice the marking scheme and weightage to understand the exam pattern and write answers accordingly.
  • Improve writing skills
    To get the maximum marks possible in the board exams, students need to understand the appropriate ways of answering questions. Look for NCERT Solutions to help you in writing answers that are presentable, descriptive, and worth the marks. Use subheadings, diagrams, pointers, etc. wherever required. Make sure that your handwriting is clearly understandable and your answer sheet is not messy, your questions are correctly numbered and in the right order.

What to keep in mind during the exam?

  • Time Management
    It is important that you finish your exam in time. Before you start answering the questions, a duration of 15 minutes is provided to read the question paper. Use the given time efficiently by thoroughly reading each question and understanding how you have to answer them. Take a note of the marks distribution and word limit for each question. As you start solving the paper, make sure you attempt the easier questions first and then move on to solving the less easy questions. In case you come across a difficult question, do not spend a lot of time figuring out its solution. Instead, move on to other questions and come back to the difficult questions after you are done solving the entire paper. Make sure you are left with some time to quickly revise and check all your answers to ensure that you have not missed any questions or answered incorrectly.


These few tips are easy to follow and will provide productive preparation and high marks in your Class 12 Biology Exam. Make sure you also keep a check on your health and regularly indulge in some physical activity as well.
