Read NCERT line by line

Make NCERT Biology your base and read every line very carefully. Don’t just read it and leave, learn it! You might find it difficult to understand and memorize at first but you’ll get used to it eventually.

NCERT is the Bible for NEET Biology and must be read with the utmost attention. I cannot emphasize enough how important it is to understand and memorize all the topics thoroughly. Don’t skip anything because questions can be asked from anywhere!

And always start from the basics. Why?

Because the journey of a thousand miles begins with a single step.

Spaced learning

Study NCERT biology on a daily basis, even if you’re studying it for a little while. Do this on a regular basis so that you can retain it in your long term memory. Since it’s a very light subject, you can literally study it anywhere, for example, while you’re commuting on your way back from school/college.

Let me give you two options, you choose which one’s better:
1. A student who studies for half an hour every day for a week. (short and frequent sessions)
2. A student who studies for 3 and a half hours once a week. (long and extended session)
Both are studying for the exact same duration a week, but for different intervals.
Who do you think will perform better?
The first student will have better memory retention.

This is known as spaced learning or spaced repetition wherein students review their textbooks again and again over a long period of time. This gives your brain a much-needed workout every time you revisit your books. Following such strategies will help you get the most out of your long term memory.

Focus on high scoring chapters

Spend a lot of time and effort on the chapters with very high weightage. NCERT Biology (class 11th and class 12th) has 10 units covering various chapters.

Since NTA has been conducting NEET since 2019, let’s consider the weightage of biology chapters according to NEET 2019 and NEET 2020. Here is the list, with the name of the chapter first, then followed by the number of questions asked from that particular chapter.

Chapter wise weightage of Biology in NEET 2019:

Animal Diversity2
Plant Morphology1
Plant Anatomy3
Structural Organization in Animals2
Cell Biology and Cell Division7
Plant Physiology9

Chapter wise weightage of Biology in NEET 2020:

Genetic and Molecular Biology8
Human Health and Disease3
Strategies for Enhancement in Food Production1
Microbes in Human Welfare2

Conceptual clarity

Some questions are such that they combine one or more concepts together. This can confuse you if you don’t have clarity in your concepts. Clear your doubts then and there if possible. Either with the help of your teacher or the Internet. Make sure your concepts are crystal clear.

I agree that some chapters aren’t well explained in NEET and you might end up with many doubts. For these chapters, strengthen your concepts with another reference book, it can be your coaching material or from any reputed publisher or you can also watch related videos on YouTube. But make sure you only study topics that are there in NCERT from these books and not go overboard. Only after reading NCERT should you consider reading another reference book/coaching material

Summarise better

The biology section of NEET mostly consists of conceptual/factual questions. Use highlighters to highlight all the important and frequently asked points that are volatile and easy to forget so that it becomes easier for you to revise the next time.

You can also make your own quick and short notes or flowcharts on flashcards and stick it in your textbook for a quick overview of the topic. This helps in revision in the last few days before the exam.


Chapters like the Plant Kingdom, Animal Kingdom, Morphology of Flowering Plants, etc contain hundreds of examples. Create your own funny mnemonics (get creative!) whenever you’re having a problem remembering them.

Take a few A4 sized sheets and write down all the examples along with their features. This will hardly take an hour or so. Go through them on a daily basis and eventually you will have all the examples at your fingertips.


Draw and practice diagrams and don’t forget to label them as well. Practicing diagrams will help you retain it in your visual memory.

If you don’t have time to draw and practice diagrams, go through them frequently so that you don’t tend to forget them. Give special emphasis on labeling.

Is NCERT enough for Biology in NEET 2021?

is ncert enough for neet biology 2021

NCERT is enough to get a good score in NEET. Your approach should be to study NCERT cover to cover, it’s sufficient for NEET 2021. About 75 questions in NEET Biology can be comfortably answered by studying NCERT only, that translates to about 300 marks. The National Council of Educational Research and Training, NCERT books help to build a rock-solid conceptual foundation. Moreover, it’s written in a simple and lucid language which is easy to understand.

If you don’t have the NCERT textbooks you can download it from their official website.

It’s up to you how you test your knowledge through problem-solving on a regular basis.

How many questions in NEET Biology are from NCERT:

If we see the general and recent trend, here’s a rough estimate:
Out of 90 questions,
70 questions in NEET Biology are asked directly from NCERT (easy/moderate level)
15 questions in NEET Biology are asked indirectly from NCERT (moderate/difficult level, which are twisted and asked from the most unexpected corners of the book!)
5 questions in NEET Biology are asked from outside of NCERT (ugh!)

So basically, if you wish to score 300 marks in the Biology section of NEET, you have to aim to get atleast 75 questions right.

How to revise entire syllabus of Biology for NEET (Revision strategy):

  • Solve NCERT exemplar for better understanding of the topic.
  • Practice MCQs and attempt mock tests on a daily basis.
  • Go through previous year’s questions to know the exam pattern.
  • Revise regularly and effectively.
  • Stay calm and confident.

Solve NCERT exemplar

NCERT exemplar books (class 11th and class 12th) are very beneficial and have HOTS (higher-order thinking skills) type of questions in MCQ format which will definitely aid in strengthening your basics and fundamentals. Sometimes, these advanced level questions are directly picked from NCERT exemplar and given in NEET.

Practice MCQs and attempt mock tests

Attempt as many mock tests as you can because it helps you to improve your speed and accuracy. Go for mock tests with high-quality questions. Don’t neglect it and don’t get disheartened if you’re scoring low, work on where you’re going wrong and be consistent in your preparation. Practicing biology is as important as practicing physics and chemistry. Mock tests will help you distinguish between gaining knowledge and applying knowledge.

Also, try to finish these mock tests within a given time frame so that you get used to it. The exam is of 3 hours, try to finish the biology section in less than an hour so that you can devote more time to solving chemistry and physics.

Give mock tests, analyze, improve, execute in the exam!

Go through previous year’s questions

Checking the previous year’s questions in both NEET and AIIMS will help you get a grip on the topics which are frequently asked which will eventually help you get get a better understanding of the level and difficulty type of questions asked in the medical entrance examination. Religiously solve at least past 10 years questions papers.

Revise regularly

Don’t leave revision for the last minute. Revise at regular intervals so that you can recollect topics and concepts in a very efficient and effective way. When you’re studying, have a balance between the easy and the difficult topics and try to focus more on the former.

Stay calm

Don’t stress out. It will only decrease your performance. Stay consistent and keep going, that’s the key. Constantly thinking about negative consequences will only downgrade your potential. Stay confident!

Good luck Medicoholics! Until next time.
