Prepare notes of all the important definitions and terminologies from each Biology Class 12 Chapter. Note-making will accelerate your learning and revision for the exam. Practice all the NCERT diagrams well. Make a habit of drawing neat habits with a pencil and give all the required labelling to the diagram in legible handwriting. Some complex diagrams cannot be mastered in one go. So, be patient, regularly practice and revise these diagrams to perform well in the Biology exam. Never hesitate to approach your Biology teacher and never turn a blind eye to your queries and doubts.  


  1. Efficiently Revise Multiple Times 

Revise every Biology topic at least 3 times before appearing for the Biology exam. Without regular revision sessions, all your hard work will go in vain. Thus, allocate weekends to revise whatever is learnt on the weekdays. Merely studying is not enough. It is extremely important to retain and store whatever learnt in your long-term memory to easily recollect answers while attempting the Biology exam. The more you revise, the better you will perform in your exam. So, revise as many times as you can to do wonders in the Biology Board exam. 


  1. Practice Previous Year Questions and Sample Papers 

Complete your Biology syllabus at least 3 months before the month of the exam. In these 3 months give 3 hour-long Mock Tests. Practice as many previous year Questions and Sample Papers as you can. Practising questions has multiple benefits. Firstly, it helps you revise and build confidence in well-understood topics. Secondly, it lets you improve quickly by helping you recognize your repetitive mistakes. And thirdly, practising sample papers helps you manage time well on the day of the exam.


  1. Manage Time well on the Day of the Exam 

Prepare your unique strategy for attempting the question paper on the day of the final Biology exam. Never try to blindly emulate the strategy of toppers. Based on your strengths and weaknesses, plan how much time should be allocated to each section of the question paper. First, attempt those questions that you know well. Then, move on to the doubtful or difficult questions. If you are stuck while attempting a question, skip it for the time being and complete answering it after you have attempted the rest of the questions. Complete the paper at least 15 minutes in advance to revise your answer sheet. 

Present answers in legible, neat handwriting. Use a pencil to underline the key terms. Present answers in a structured manner and try to write answers in points instead of paragraphs. Give adequate spacing in between two answers. Avoid overwriting and unnecessary scribbles. Ultimately, your answer presentation will make your answers stand out and will fetch you a perfect score in the Class 12 Biology exam.


In conclusion, you can easily ace the Class 12 Biology exam by implementing these tips. Except for working hard for your Biology exam, you must prioritize your health to perform your best on the day of the exam. Take adequate sleep daily, eat nutritious food, keep your body well hydrated and exercise regularly. Take care of both your physical as well as mental health. Devote a few minutes every day towards self-care and meditation. Take short breaks between study sessions. Be assured that if you consistently work hard throughout the year, success is all yours in the Biology exam. All the best!
