Biology doesn’t only involve learning

Often students complain that in Biology they only need to learn various biological terms which is quite boring but you can read it from CBSE Question Bank Class 12 Biology 2025-2026 for understanding biological terms. But chapters like Genetics and Biotechnology do not require only learning work. You need to understand them well to score better in the exam. If you succeed in understanding different topics of Genetics, then it will become the easiest chapter in Biology. Otherwise, you will find it difficult to prepare Genetics and Biotechnology.  

How to learn difficult Biology terminology? 

The best tip to learn the difficult biological terminology is to write them on paper many times. By writing you can memorize any biological terms. Suppose you need to learn the genus of a Baculovirus i.e., “Nucleopolyhedroviral”. Undoubtedly it is a big term, but you can easily learn it by writing the term repeatedly on paper. 

Importance of Diagrams in Biology:

Diagram is very important in Biology. Even in medical exams like NEET and AIIMS, many diagram based questions are asked these days. Hence you should fully concentrate on various biological diagrams. There are many questions in Biology like- How Hershey and Chase proved that DNA is the genetic material? Theoretically it is a big question, but you can answer this question by drawing diagram of the experiment conducted on Bacteriophage by Hershey and Chase too. And you will get full marks for it in the board exam.
