Important Chapters for JEE Main 2020
The first thing to know is that NTA does not allocate any weightage to any chapter and you should try to learn and understand all chapters of all subjects. You should have a complete understanding of all the concepts and formulae of all the chapters and topics. You must have all the concepts on your tips. Once you have conceptual clarity of the important topics, you should practice questions based on the important chapters for JEE Main. By following this way, you will be able to target the maximum marks without worrying about all the chapters. More importantly, if the students have complete command over these important chapters, they are destined to score great marks in the JEE exam.
After analysing the pattern of the past years' question papers of JEE Main, subject experts have prepared a list of the important chapters.
*Also, these chapters have been categorised into 4 different categories based on the number of efforts needed to learn and score in the exam along with the weightage of the chapters.
