The exam conducts by NTA ( National Testing Agency ) every year. JEE Mains & JEE Advance are the two branches of JEE. As a student who wants to secure a sit in the top IIT ( Indian Institutes of Technology ) has to appear in the JEE Mains, and once a candidate passes the JEE Mains with an excellent score then they can appear for the JEE Advance.

Now some of you might think, why teachers and parents puts so much pressure on scoring well in the JEE Mains & JEE Advance exam.

So the answer is, the better you score and rank obtain in JEE Mains & JEE Advance examination, the better IIT institute you’ll get.

Not only this, a top scorer gets a chance to select their favorite branch of study & IIT institute.

Now, normally the National Testing Agency conducts two sessions of JEE, January session, and April session.

Talking about the April session, NTA conducts it from 5 to 11. And the January session held from 6 to January 9.

But because of this whole coronavirus thing, NTA canceled the January and April sessions. And now they decided to conduct the exam from September 1 to 6, 2020.

According to some stats, more than 1.4 Million or 14 lakhs of students apply for JEE Mains every year.

In order to secure a sit in institutes like IIITs ( Indian Institutes of Information Technology ), NITs ( National Institutes of Technology ), and other Government-funded Technology Institutes (GFTIs) and become a successful engineer.

But unfortunately, only 250k or 2,50,000 students gets admission, and rest 1.1 million or 11,50,000 students have to apply again next year.

But all I can say IIT JEE is one of the toughest entrance exams of our country. It requires a lot of patience, hard work, the right strategy, and a perfect study plan.

So if you are one of those passionate JEE Mains aspirates, then going through this complete guide on how to prepare for Jee Mains will help you to crack the JEE mains examination. So without any further due, let’s get started!

What is JEE Mains?

The JEE or you can say Joint Entrance Examination is an EEA, now the means of EEA is Engineering Entrance Assessment.

This JEE exam allows the aspirate to get admission in various engineering colleges in India. The JEE is made of two different exams, the first one is JEE Mains and the second one is JEE Advance.

Based on the rank and score of a student or aspirate gets in the JEE Mains & JEE Advance exam.

They’ll get a chance to choose institutes from 32 NITs campuses ( National Institute of Technology ), 24 IITs campuses ( Indian Institute of Technology ), 18 IIITs campuses ( Indian Institute of Information Technology ), and 19 other GFTIs ( Government Funded Technical Institutes ).

Also, many more institutes like IISERs ( Indian Institutes of Science Education and Research ), RGIPT ( Rajiv Gandhi Institute of Petroleum Technology), IISc ( Indian Institute of Science ), IIST ( Indian Institute of Space Science and Technology ), and IIPE ( Indian Institute of Petroleum and Energy ) give admission to a student based on the score and rank they get in JEE Advance examination.

Subject wise Preparation Tips

In the JEE Mains examination you’ll face three main subjects Maths, Physics, Chemistry. I see many students make a mistake of giving more importance to one subject.

But remember if you want to clear the JEE Mains exam, then you’ll have to give all subjects equal importance and time. Below I have given some tips on how you can prepare these three subject:-


Mathematics is one of the most important subjects; that is why it becomes a little challenging to deal with it. But to overcome this problem or challenge, you do one thing.

You can list out most scoring topics of JEE Mains mathematics. Now practice these topics so that you can develop a habit of solving the math problems which will come from those most scoring topics.

By doing this, you can also create your way or shortcuts to find the answer within no time. This will help you to save your precious time during the exam.


Chemistry is a mixture of many things, such as theory, concepts, chemical equations, and many problems. Generally, many JEE candidates ignore the subject because it takes a lot of memorization.

There are three phases of chemistry Physical, organic, and inorganic chemistry.

Each stage require the different skill of your, like inorganic chemistry will test your memorization, physical chemistry is purely analytical, and organic is a balance of both.


If you ask a JEE Mains aspirants which subject do you fear the most? I am pretty sure the majority of students will answer physics.

But if you have an in-depth knowledge of concepts and you know the difficulty level & weightage of various topics, then it becomes relatively easy to tackle it. Because in the end, physics is all about concepts and logic.

Some Important Tips on JEE Mains Preparation

  1. Focus on managing your time. I mean give equal preparation time to each subject. Along with all this, find out some time for playing.
  2. Try to understand the concepts instead of just memorizing them.
  3. Self-analysis is important so that you can find your weak and strong sections. Once you identify the weak areas, then you can work on those areas.
  4. Give at least 40% of your time to your board exam preparation, so that you’ll have a balance between JEE Mains and your 12th boards.
  5. If you have doubts about any concept or anything else, clear it right away, don’t wait. Because these problems or doubts can hold your further learning.
  6. Knowing the JEE Mains pattern and its syllabus is a must, so before doing anything know about the pattern and syllabus of JEE Mains.
  7. Using the right book is really important. Now you may think about which books should I use for JEE Mains. So don’t worry about that, because I have mentioned all the books you’ll need in your journey.
  8. Revision is a must, cause if you don’t revise what you studied then the chances of forgetting the topics can be increased.
  9. Give more time and importance to high scoring topics.
