How to utilize Class 11 Biology NCERT Solutions for Board and Competitive exams?

Biology is a subject that tells us all about the natural world. Just like the other disciplines of science, it tries to explain the various phenomenon, events, or organisms with the help of observation, experimentation, and documentation. Here are a few tips you need to learn to study biology.


Diagrams are the prominent part of NCERT class 11 biology syllabus. In the exam, though, you will not have much time to draw neatly or clearly, and this, in turn, might prevent you from getting the marks you need to score well in the exam. Therefore, practice the relevant diagrams with some aspects such as shading and texturing beforehand. Doing this will make you stand out from your fellow students. Now, this might take some time to develop and get good at, but the reward is worth it.

Breaking down Information

The sheer magnitude of information might make it hard for you to remember everything. That’s why you need to develop a technique called information chunking, where the information is broken down into small chunks, and this makes it easier for the student to process the information. This is very effective because the cognitive load is reduced, and this, in turn, slows down mental fatigue. How you split the information is entirely dependant on you and your abilities.

Note Taking

Everyone already knows this, but not everyone implements it. This technique is underrated but incredibly helpful from an examination point of view. Whenever you are attending a lecture, make sure you note down the crucial points that the teacher says. This process stimulates your thinking, and you can recall information more easily. Furthermore, this is an essential tool to use when you revise for your exam. Since you prepare these notes, you will find it easier to comprehend and recall the information than any other textbook.
