Most important Topics for JEE preparation

What are the most important topics for JEE preparation?

Studying the vast topics in all 3 subjects – Physics, Chemistry and Maths are not less than a humongous task.

IIT JEE Main & Advanced Test Series

And to complete all this huge syllabus in 1 or 2 years, you need to study smart – concentrate on topics that are tough and have more weightage and let go of topics that are not needed at all.

A huge disclaimer before we begin – JEE (Joint entrance exam) is a 50 – 50 shot at predictability. What does this mean?

Even though there are topics that have less weightage from JEE standpoint, you still need to study them as you never know – You might end up getting an entire 10% of a subject from one of the least expected sections.

So, do not waste a single moment of these 2 years of your JEE Preparation, study, solve problems, revise and most important of all – stay calm.

“I was going through online forums and to my surprise, students are asking the same questions over and over again when they get overwhelmed with JEE Syllabus. Do you know what these questions are?”

“What are some of the most important and heavily weighted chapters for JEE Advanced (subject wise)”

“Which chapters are important for JEE mains and advance 2017”

“Is gravitation one of the most important chapters for JEE-Advanced?”

“I have only one year for my JEE Main 2017 preparation. Which topics should I focus more to get good marks in JEE Main 2017 exam?”

Do you see what is common – everyone wants to focus just on the important topics and skip other topics. This is something you should try not to do – you must study all the topics in the syllabus and lay more stress on the important topics.

Lets start by taking a look at the important topics for Physics in JEE Main & Advanced

Important topics for Physics in JEE Main & Advanced

The physics portion for JEE has 20 chapters, all in all, that have to be covered over 2 years time. Of these 20 chapters, there are 10 topics which you should spend good amount of time on:

  • Dimensional Analysis – Although a very easy chapter but knowing correct units and dimensions for physical quantities can easily help you to eliminate options in multiple choice type of questions
  • Gravitation & Electrostatics – These chapters are conceptually similar to each other (in terms of attractive forces concepts)
  • Current Electricity & Heat Transfer – again these are conceptually similar to each other. So, when you read these chapter watch out for the similarities (which might be deceiving at times)
  • Electromagnetic Induction, Waves & Sound
  • Geometrical Optics , Thermodynamics
  • Kinetic Theory of Gases, Rotational Dynamics

These 3 are the most basic concepts that you  ought to know. You can expect at-least 1 question from these topics:

  • Units and Dimensions – Weightage: 2%
  • Measurement of Errors – Weightage: 2%
  • Vectors

These topics are classified as fundamentals in physics. You can expect 1 – 2 questions from this section on an actual JEE Paper.

  • Kinematics – Weightage: 1%
  • Newton’s Laws of Motion – Weightage: 4%
  • Friction

These 5 topics are important & easy and can help your score high marks very easily in the JEE:

According to Pankhuri K (BIT Mesra, Architecture) concepts like SHM (Simple Harmonic Motion) were used even in her engineering studies. She also recommends watching tutorial videos for getting clearer conceptual understanding.

And finally, here is a list of the topics that you should study atleast once and try to create cheat-sheets or flashcards to help your revise the formulas. You can expect 3 – 4 questions mix and match from the topics below.

  • Circular Motion – Weightage: 1%

MeritNation Expert Payal Krishnan says that JEE Advanced has some different syllabus requirements from JEE Main and students should make sure they study all the topics and not skip things trying to do selective study.

She also adds that this will help students after they qualify JEE Main as they would not have to spend extra time for JEE Advanced preparation

By average Number of questions asked in past JEE Main / Advanced Physics papers:

  • Current Electricity: 8 questions asked on the actual JEE paper each year on an average
  • Electrostatics: 4 questions
  • Optics: 3 questions
  • Heat and Thermodynamics:  2 questions
  • Law of Motion: 2 questions
  • Waves: 2 questions
  • Simple Harmonic Motion: 2 questions

You can expect some more questions (mix and match) from the other topics in the syllabus.

Important topics for Maths in JEE Main & Advanced

Mathematics is the foundation of complex engineering calculations. You must make your Math fundas strong if you want to pursue any engineering field out there be it Computer Science or Mechanical Engineering.

One thing you must understand early on is that Math is one subject where you can master yourself only by more and more practice. Some Physics & Chemistry problems can be solved just by knowing formulae, but Maths – you gotta practice hard and practice smart!

The JEE Syllabus for Maths has close to 15 chapters which you have to cover over a period of 2 years (Class 11 and Class 12).

Unlike Physics or Chemistry, there is no such section that you could probably skip to concentrate on the important topics as in Maths, there is nothing called a very important or a less important topic. Everything is dependent on one another, so you will be better off practicing problems from all the 15 chapters in the Maths syllabus for JEE.

List of important Topics in Maths for JEE 2017 By Syllabus Weightage

These topics have been classified as fundamentals in Maths. You can expect 1 – 2 questions from these topics in the Maths section on your JEE paper.

  • Inverse Trigonometric Functions – Weightage: 2%
  • Circles and Family of Circles – Weightage: 6%

These 7 topics are absolutely important for JEE Maths. As it is, you can expect questions of varied difficulty from the topics in this section. For JEE Main 2017, 2 – 3 questions from most of the topics listed below are expected on the paper.

  • 3-D Geometry  – Weightage: 5% Questions from this topic are generally straight forward so you can solve them easily by reading the questions properly.

Important topics for Chemistry in JEE Main & Advanced

There are 25 chapters (or topics) in the prescribed syllabus for Chemistry in JEE Main & Advanced. I was one of those students who was not a big fan of Chemistry but still managed to get a decent score. How?

Well, Chemistry is one of those subjects which you can study selectively and still aim for a cent percent marks. This is because most of the concepts in Chemistry revolve around bond formation, breaking and the periodic table.

So, if your fundamentals in these topics are rock-solid then your life will be so easy while you prepare for your JEE Main or advanced exam.

Here is a brief overview of the important topics in Chemistry:

  • Chemical Bonding & the periodic table – This is by far the most fundamental and the most important topics in Chemistry. If you can master Chemical Bonding and the properties of periodic table elements, then Chemistry will be an easy subject for you over many years to come.
  • Carbonyl Compounds & their derivatives
  • Redox reactions, Mole Concept & the concept of equivalents
  • Solid state, solutions & gases theory
  • Thermochemistry & the Second Law of Thermodynamics (Remember, I had told you about this in the Physics section)

Fundamental Concepts:

  • IUPAC Nomenclature
  • Periodic Table
  • Chemical Bonding – Weightage: 5%. Like I mentioned earlier, Chemical Bonding and periodic table is one of the strongest pillars of your CHemistry conceptual understanding. You can easily get top ranks by making sure your concepts are crystal clear on this topic.
