How to prepare and score Good marks in Biotechnology Paper?

Prepare a good timetable

  • A maximum of 3 hours, daily will be more than enough to score well on your boards. You should honestly utilize these 3 hours from your daily schedule and study well for your board examination.
  • Do not study for longs hours continuously. This way of studying can leave you exhausted. You should always take small breaks in between. You can eat something you like, go out for a healthy walk, or you can take a nap. You can go back to study, once you feel fresh.
  • Keep your timetable flexible. In case you feel exhausted or sleepy, you can change your timetable and have a healthy break in between
  • Never ever compromise with your health. Do not skip your meal or study without sleeping well. You should sleep for 7 to 8 hours minimum. This will help to keep yourself healthy. Health is Wealth, after all.


Solve All The CBSE Previous Year Question Papers – The best way to check your preparation level well, is to solve CBSE Previous Year Question Papers. Honestly solve these papers, like the way you will be solving the actual board’s paper. After you’re done solving, analyze what mistakes you made and. This will help you identify the topics you need to give special attention to.

Go Through online test series class 11th – Several class 11th practice tests for biotechnology are present on the internet. You can start solving these online test series class 11th after you are done solving the previous year papers. These class 11th practice tests will help you have a better practice of the subject and prepare you for your boards.

Have a good reference material (CBSE Study material/ CBSE Study notes) – The ideal study material that you can keep as a reference while you are studying are these CBSE Study material/ CBSE Study note. Toppers notes are also available for the internet for your reference. These toppers notes and the study materials have the accurate and up to date information which is necessary for good exam preparation. Prepared by experts in Biotechnology, these reference notes will boost up your preparation and will help you attain success in your exams.

Know your exam pattern and the syllabus well – Having a thorough knowledge of the exam pattern and the syllabus will help you prepare a good strategy for your preparation. Try to complete the harder chapters first and then study the easier ones. This way, you will be free from any tension and can study patiently during your exam days.
