How to Prepare Biology for NEET 2021?

Every subject requires a different technique of preparation and the exam for which it is being studied also has a major role to play in its preparation strategy. Some simple and necessary steps that have to be taken while preparing for the subject of Biology for NEET are provided here. Candidates preparing for NEET 2021 can take help from these steps while beginning with their Biology preparation for the exam.

  • One of the most important steps that must be taken into account before starting the preparation of Biology for NEET 2021 is planning. Students must plan their studies beforehand and go about the details gradually. Making a schedule or a time table for proceeding with your Biology preparation is extremely important. Students should make a time table for regular studies and allot time to all the topics of the subject according to their understanding. However, the benefit of such a schedule can only be availed if the student sticks to it and follows it without fail. They must ensure that they study every day as per the schedule that they have devised.

  • Choosing a convenient and helpful preparation strategy is another important step that students must never forego. It is always considered wise to pick up those topics and chapters which carry high weightage. Some topics take more time for preparation than others and some need to be memorised more. Focusing more on topics from which a decent number of questions are asked in the exam is considered a wise move as it helps to increase the chances of scoring significantly more marks.

  • Consulting good books from reputed authors and publications is essential because students must refer to content which is correct and valid. There are some renowned authors whose books are studied by all NEET aspirants for preparing for the subject of Biology. A lot of focus is given to NCERT books for preparing Biology for NEET.

  • Making tables, charts, and personal notes prove to be quite helpful while preparing Biology for NEET. As Biology is a theoretical subject and there are a lot of topics that need to be memorised by students, it becomes convenient if they prepare notes and tables of those topics. Breaking such chapters into smaller sections and fragments gives much more clarity and the student can then retain the information easily for much longer. The usage of different colours of inks, highlighters, flowcharts, bulleted lists, etc. is of great assistance in making such notes.

  • Regular revision is mandatory in the preparation of Biology for NEET. Only with frequent revision, students can memorise all the theoretical parts of the subject clearly. Revising on a daily basis does not let any confusion reside in the minds of students. It also ensures that the course content stays fresh in the memory of students. Students can also keep track of their progress in the subject by revising all the topics regularly.

  • Taking mock tests is one of the major and most important parts of preparing Biology for NEET. Students must take as many mock tests as possible before they appear for NEET 2021. Practising mock tests helps the candidates in gauging their preparation and performance. It also gives them an understanding of the type of questions that will be asked in the exam. The candidates get to know which topics do they have to focus on more than the others and the approaches they should apply to certain questions. Mock papers and old questions papers prepare the NEET aspirants for giving the exam.
