What are the most important chapters to score a three-digit rank in JEE Main?

Scoring a three-digit rank in JEE Main is very much possible with some dedicated efforts and thorough practice. Since the exam is easier as compared to other engineering entrances (read: JEE Advanced) many students give it with their board-level preparations and a few extra efforts. So, knowing the important topics for the last month's preparations helps a lot. Thus, go through the following list and know the most important chapters for JEE Main.

Important chapters for JEE Main Physics:

Physics has a lot of theoretical chapters which are done at the end of class 12th. One shouldn’t skip them as they are easy and scoring and since they are only coming for JEE Main they are bound to be asked in it (for example, semiconductors). The other important chapters are as follows:

1. Current electricity: This chapter is taught in class 12th and forms an important chunk of the JEE Main. Doing this chapter will simplify a few other topics too as it is analogous to some portions of electrodynamics.
2. Modern physics: This portion is mostly learning and concept based. It is easier as compared to other topics and fetches some easy marks.
3. Electrostatics: It forms an important part of the JEE Main physics and its questions can be tough at times too.
4. Rotational motion: It is a very vast chapter but once you understand it well; its questions will be really easy to solve especially in JEE Main.
5. Oscillations and waves.

Important chapters for JEE Main Chemistry:

Chemistry roughly has 10 questions from each of organic, physical and inorganic portions each year. Chemistry has a vast syllabus and should be prepared smartly as there is a lot of learning to do. Also, it is the least time taking when compared to the other two subjects. Here are the must-do chapters for JEE Main chemistry:

1. Equilibrium: Consisting of both ionic and chemical equilibrium, it is an important portion of physical chemistry and is asked in a majority of the paper.
2. Aldehydes, ketones, and acid: Mostly this section of organic chemistry is asked in the form of named reactions.
3. Coordination compounds: It is an easy and conceptual chapter and is pretty important and fetches easy marks too.
4. Heat and thermodynamics: This chapter is present in the physics and chemistry syllabus and the difference is only a few rules so doing this one will help both ways.
5. Biomolecules and polymers: This is the most boring part of chemistry and is skipped by a lot of aspirants. But this is just rote learning and if done properly can fetch lots of quick marks.
6. Chemical bonding: It is a conceptual portion of inorganic chemistry and is always asked in a good number.

Important chapters for JEE Main Mathematics:

Mathematics is very scoring but it gets too long at times. Know the important chapters of mathematics to prepare wisely and maximize your score:

1. Probability and permutation-combination: This is very logical and every year JEE makes new and interesting questions on these topics. Being a fun topic, it seems like the favorite topic for JEE mathematics.
2. Coordinate geometry: This again is a vast topic but from among its sub-units, straight lines and circles are the most important. Knowing its formulas is very important.
3. Integration: Out of definite and indefinite integration, definite is more important. It must be prepared thoroughly.
4. Vector and 3D: This is the last portion of JEE Main mathematics and is widely asked. For this, imagination power needs to be good, and practicing surely helps a lot.

JEE Main is all about speed and accuracy. Practice a lot of mock tests and you will surely excel. Don’t skip out any of the above topics!

All the best!
