The Most Important Chapters for JEE Advanced Physics, Maths, and Chemistry

As you prepare for JEE Advanced, many questions must be going through your mind, like ‘how should I prepare?’, ‘what should be my time table?’, ‘how I should prioritize chapters for this exam?’. Well, acing an exam mainly boils down to how you have planned to prepare for it in right way. In this era of cut-throat competition, planning is as important as actual studying, just like being intelligent or dedicated isn’t enough. You have to be a smart and hard working student.
In this post, I have written about important chapters for JEE Advanced, to help you prioritize chapters to get an awesome rank in the exam!

Important Chapters for JEE Advanced Mathematics

For Mathematics, you need rigorous practice. The more problems you will solve, the better will be your speed and accuracy.

The syllabus of Maths is broadly divided into:

  • Algebra
  • Trigonometry
  • Calculus
  • Co-ordinate geometry
  • Vectors and 3-D geometry
  • Probability
  • Complex numbers

Below, I am writing about chapters as how you should prioritize them.


Calculus includes chapters on functions, limits, continuity, differentiability, differentiation, application of derivatives, integration, definite integrals and differential equations. Each of the above topics is important, and the calculus section covers around a third of the paper. So, you must be well-versed with every standard formula and technique used in calculus.

Co-ordinate geometry

This topic is again very very important. This topic is all about understanding Circles, Parabola, Hyperbola, Ellipse, and using correct formula at correct place. Easy and scoring topic. Solving sufficient problems during practice will ensure you to solve problems in JEE advanced from this topic.

Vectors and 3D geometry

Having done the coordinate geometry portion, most of you will find the 3D geometry portion relatively hassle-free and do well in this section. It’s primarily easy-breezy because JEE contains numerous problems pertaining to vectors that require standard formulae .


Algebra questions in JEE are a bit hard, and most students struggle with the chapters on permutations and combinations and complex numbers. However, practice is the key. The chapter on complex numbers greatly depends on the coordinate geometry portion. At times, a hard question from complex numbers can be solved if one can smartly correlate it to a coordinate geometry problem.


Probability is again an important topic. Having gone through its problems and understanding the concepts of Bayes theorem etc. properly, you can solve most of the problems of JEE advanced. And even if you are not able to solve problems in JEE, don’t worry, very few students are going to solve that. You can use common sense in some of the problems.


The formulae of trigonometry appear everywhere in JEE Mathematics exam paper. Very few questions are purely based on trigonometry, but there are always questions that involve standard trigonometric identities. Remember that an important aspect of the JEE Mathematics preparation is memorizing standard formulae. Make sure you remember them by heart.

Finally, to master JEE maths, you need lot of practice. Keep practicing and enjoy maths.

Important Chapters for JEE Advanced Physics

Physics requires you to have a strong hold on concepts. Once the concepts have been mastered, they are very easy to retain. Some chapters of JEE physics have a heavy weightage in the exams.


Mechanics is probably the most important topic in physics from JEE perspective. A bulk of questions in JEE are either directly mechanics questions or require you to have considerable skill in mechanics, which will help you solve a part of the question.

There are some of the most fundamental laws – Newton’s laws of motion, universal law of gravitation, the law of conservation of linear momentum and so on. You must know how and when to apply formulas and these laws properly.

Some of the problems also requires basic calculus knowledge, so take care of that part too.
Study fluid mechanics, Bernoulli’s equation, elasticity seriously.

Electrostatics, Current electricity, and Magnetism

This is another big section of JEE and among the most important chapters for JEE. A lot of questions are asked from the applications of Coulomb’s law and Capacitance. Stick to the JEE syllabus because this topic is diverse.

Don’t be scared of complex circuits and try to use the fundamentals to reduce complicated circuits to simpler ones. Use Kirchhoff’s laws, series parallel reduction and such tricks. Do not ignore the theoretical aspects of the topic. There are quite a large number of standard formulae in electrostatics and magnetostatics. Make sure to remember them all (with directions involved) because you won’t have enough time to derive standard results on D-day.

Motional EMF is one of the most asked topics and should be among the top priority chapters for JEE, so ensure that you practice ample of questions from it.

Thermal physics and Sound waves

This chapter covers a big chunk of the paper too. Since the topics are diverse, don’t be surprised to see a question which is a mix of calorimetry with the laws of thermodynamics. Familiarize yourself with calculations of work, internal energy and heat in various processes.

A lot of questions are asked from waves and sound; the most common ones are from Doppler Effect.

Optics and Modern Physics

Optics isn’t as difficult as it seems; it is indeed one of the easiest topics for JEE. Practice many questions, and you’ll be able to master it. Do not ignore Huygen’s principles.
Modern Physics is mostly theoretical. In this, the focus should be on understanding the nuances of Bohr’s model. The common formulae should be memorized.


JEE Advanced also contains problems related to experiments like error analysis in vernier callipers, screw gauge, and questions from potentiometer. So, practice questions from these portions.

Important Chapters for JEE Advanced Chemistry

One must understand that it’s very important to read as much as possible in order to learn chemistry. Also, revision is crucial as there’s a possibility of forgetting things. Take chemistry as seriously as mathematics and physics. Do not ignore this subject just because you feel chemistry is purely “cramming.”

Weightage is nearly equally distributed in the three streams of chemistry. It is important not to skip any topic from Inorganic Chemistry as the subject is highly scoring.

Physical Chemistry

Physical chemistry has nothing difficult in it. It’s all about understanding the concept and applying formulas at correct places. All simple. Understand Mole Concept and topics like Chemical Equilibrium, Chemical Kinetics, Electrochemistry are all derived from it, and you will find these topics easy.

Put some efforts in understanding Thermodynamics and Atomic Structure by solving problems.

Organic Chemistry

The key to understanding the entire organic chemistry is being thorough with the general organic chemistry section – electrophiles, nucleophiles, types of reaction, acidity, basicity, etc. The remaining organic chemistry is just the application part.
E.g. Knowing that a reaction consists of a nucleophile attacking an electrophile; the only remaining bit is writing the mechanism.

Named Reactions

A large part of organic chemistry consists of standard “named” reactions and students are expected to know these reactions along with the mechanisms. It is always good to know the mechanism of a specific reaction so that you can solve a similar new problem. Still, you should learn and memorise all the named reactions with exceptions too (exceptions are also very important!).

Inorganic Chemistry

All the chapters of Inorganic chemistry are very important. Please read all the chapters from NCERT at least 5 times line by line. Many questions are from p-block, making it the most important chapter. Read from chemical bonding to s,p,d,f block to metallurgy. There will be one question at least from each chapter.

A good knowledge of periodic table and the trends in the properties of atoms (ionization potential, atomic radius, electronegativity, electron affinity, electrode potential) will help you to understand the reactions.
Finally, it all depends on how hard (and smart) you work for this exam. I wish you all the best!
