If you are going with vast and wide topics which are not important for JEE Main point of view, you are wasting your time. Also, you are leaving those topics which are really important which can affect your result.

Some questions/topics are those, which you don’t understand but you have to be prepared for them too.

So If you try to follow the experts then they will suggest you to not leave any topic and prepare them according to their weightage.

Some of the questions asked by students to experts through different forums are as follows:

What are the important topics for JEE Main according to the weightage?

What are the important topics to be prepared for JEE Main ?

I prepared only one year, can you suggest some important topics which must come into the exam?

Is gravitation an important topic for JEE Advanced ?

Which topics should I focussed more to crack JEE Main  with good score?

So once you analyze all the questions you will get what everyone wants to find-out what are the important topics for JEE Main ?

Now I am discussing some important topics for every subject i.e.

Important topics for Physics in JEE Main & Advanced :

Once you go through the JEE Main Physics Syllabus you will find 20 chapters there, out of 20 you have to spend good amount of time with these given 10 chapters as compared to others.

Dimensional Analysis

Gravitation

Electrostatics

Current Electricity

Heat Transfer

Electromagnetic Induction, Waves & Sound

Geometrical Optics

Thermodynamics

Kinetic Theory of Gases

Rotational Dynamics

Basic concepts you need to know, these questions generally carry 1 mark each

Units and Dimensions

Measurement of Errors

Vectors

Fundamental concepts which carry 2 marks each

Kinematics

Newton’s Laws of Motion

Friction

Easy topics which can help you to score good marks in JEE Main

Work, Energy and Power

Electrostatics

Current Electricity

Wave Optics

Ray Optics

Absolutely important questions which carry 2-3 marks each

Centre of Mass, Momentum and Collision

Rotational Dynamics

Simple Harmonic Motion

Fluid Mechanics

Wave Motion and String Waves

Magnetism

Heat & Thermodynamics

Nuclear Physics

Modern Physics

Important topics for Mathematics in JEE Main & Advanced :

Mathematics is the only subject where you can score well. If you want to pursue engineering degree from any recognised university, you need to clear your own maths fundas. By doing continuous practise you can make yourself a master of mathematics. Smart approach and continuous practise you can get success in this section.

Topics which carries 1-2 marks from the fundamental section

Inverse Trigonometric Functions

Circles and Family of Circles

Sequence and Series

Topics which are easy and important, you should use them to improve your score

Applications of Derivative

Limit and Continuity

Matrices and Determinants

Straight Lines and Pair of Straight Lines

If you are in practise and attempting 4 to 6 question from each section you will become the maths master.

Topics carrying 2-3 questions are also very important

3-D Geometry

Probability and Statistics

Vector Algebra

Integration

Complex Numbers

Parabola

Trigonometric Ratios

Topics which you have to go through once during preparation

Logarithms

Quadratic Equations

Theory of Equations

Sets, Relations and Functions

Differentiation

Permutation and Combination

Binomial Theorem

Locus

Hyperbola

Ellipse

Fundamentals of Mathematics

Solution of Triangle

Topics that were asked previous year JEE Main/Advanced

Coordinate Geometry

Continuity/ Differentiability, Limits

Complex No., Quadratic Equation

Integral Calculus

Sequence and Series

Trigonometry

Important topics for Chemistry in JEE Main & Advanced :

This is also a vast section for preparation but this is the section where you need only conceptual learning because once you have all the knowledge about the concept, you are able to solve all the questions in minimum amount of time. This section is fully dependent on your accuracy and speed. You can save your time by solving it fast and minimum amount of time. The time you saved from here you can utilize it for others sections.

Chemical Bonding & the periodic table

Carbonyl Compounds & their derivatives

Redox reactions, Mole Concept & the concept of equivalents

Solid state, solutions & gases theory

Thermochemistry & the Second Law of Thermodynamics
