JEE Main Syllabus: Subjects & Chapters
Select your preferred subject to view the chapters

Changes in JEE Main Question Paper

There is a significant difference between JEE Main question papers as compared to previous years, with respect to exam syllabus, exam pattern, number of questions etc for Paper 1 (i.e. for B.E./ B. Tech). Let's discuss them one by one

  • JEE Main Syllabus:- Major chapters from all three subjects have been deleted from the current JEE Main Syllabus with respect to previous year JEE Main Syllabus.

Here are the details about the syllabus that is removed.

Subject

Chapter Name

Physics

Communication System

Physical Chemistry

States of Matter

Surface Chemistry

Inorganic Chemistry

General Principles and Processes of Isolation of Metals

Hydrogen

S-Block Elements (Alkali and Alkaline Earth Metals)

Environmental Chemistry

Organic Chemistry

Polymers

Chemistry in Everyday Life

Mathematics

Mathematical Inductions

Mathematical Reasoning

The above-mentioned chapters are completely removed from the JEE Main Syllabus along with major topics from other remaining chapters also reduced.

For detailed analysis have a look at JEE Main Syllabus

  • Exam patterns:-

  1. Total marks- The total marks are the same. I.e Students can achieve a maximum of 300 marks in the main exam.

  2. No of Questions- Let's have a look at Subject wise distribution of the total number of questions for the JEE Main exams.

Subject

No of Questions

No of Questions

Mathematics

(20 MCQs+ 5 NAT)

(20 MCQs+ 5 NAT)

Physics

(20 MCQs+ 5 NAT)

(20 MCQs+ 5 NAT)

Chemistry

(20 MCQs+ 5 NAT)

(20 MCQs+ 5 NAT)

Here MCQs mean Multiple-Choice Questions and NTA means questions whose answers are to be filled in as a numerical value. So to summarize in JEE Main for section B in each subject 5 NTA-type questions are there, but candidates have to attempt all 5 of them.

Few Solved Questions from JEE Main 2020 Paper

1. (Subject - Physics, Chapter - Optics, Shift - 06 Sep - Evening Shift)

Question:- A double convex lens has power P and the same radii of curvature R of both surfaces. The radius of curvature of the surface of a planoconvex lens made of the same material with power 1.5 P is :

  1. 2R

  2. \frac{R}{2}

  3. \frac{3R}{2}

  4. \frac{R}{3}

Answer- 4) \frac{R}{3}

Solution:-

1720600855410

\mathrm{R}_{1}=\mathrm{R}_{2}=\mathrm{R} \\ Power= P \\ \text{Refractive index is assume} (\mu_{l})

\mathrm{P}=\frac{1}{\mathrm{f}}=\left(\mu_{l}-1\right)\left(\frac{2}{\mathrm{R}}\right)

1720600856679

\begin{aligned} &\mathrm{P}^{\prime}=\frac{1}{\mathrm{f}^{\prime}}=\left(\mu_{\ell}-1\right)\left(\frac{1}{\mathrm{R}^{\prime}}\right)\\ &P^{\prime}=\frac{3}{2} P \end{aligned}

\begin{array}{l} \left(\mu_{\ell}-1\right)\left(\frac{1}{\mathrm{R}^{\prime}}\right)= \frac{3}{2}\left(\mu_{\ell}-1\right)\left(\frac{2}{\mathrm{R}}\right) \\ \\ \therefore \quad \mathrm{R}^{\prime}=\frac{\mathrm{R}}{3} \end{array}


Hence, The correct option is (4)


2. (Subject - Maths, Chapter - Integral Calculus, Shift - 03 Sep - Evening Shift )

Question:- If \int \sin ^{-1}\left ( \sqrt{\frac{x}{1+x}} \right )dx=A(x)\tan ^{-1}(\sqrt{x})+B(x)+C, where C is a constant of integration, then the ordered pair (A(x),\; B(x)) can be?

  1. (x+1,\; -\sqrt{x})

  2. (x+1,\; \sqrt{x})

  3. (x-1,\; -\sqrt{x})

  4. (x-1,\; \sqrt{x})

Answer- 1) (x+1,\; -\sqrt{x})

Solution:-

Given,

\int \sin ^{-1}\left ( \sqrt{\frac{x}{1+x}} \right )dx=A(x)\tan ^{-1}(\sqrt{x})+B(x)+C,

\begin{array}{l} \text { Put } x=\tan ^{2} \theta \Rightarrow d x=2 \tan \theta \sec ^{2} \theta d \theta \\ \int \theta \cdot\left(2 \tan \theta \cdot \sec ^{2} \theta\right) d \theta \end{array}

Now do the integration by parts

\\\mathrm{\theta\rightarrow 1st\;function}\\\mathrm{2\tan\theta\sec^2\theta\rightarrow 2nd\;function}

\begin{array}{l} =\theta \cdot \tan ^{2} \theta-\int \tan ^{2} \theta \mathrm{d} \theta \\ =\theta \cdot \tan ^{2} \theta-\int\left(\sec ^{2} \theta-1\right) \mathrm{d} \theta \\ =\theta\left(1+\tan ^{2} \theta\right)-\tan \theta+\mathrm{C} \\ =\tan ^{-1}(\sqrt{\mathrm{x}})(1+\mathrm{x})-\sqrt{\mathrm{x}}+\mathrm{C} \end{array}

A(x)=1+x,\;\;B(x)=-\sqrt x

Hence, the answer is the option 1.


3. (Subject - Chemistry, Chapter - Hydrocarbons, Shift - 08 Jan - Morning Shift)

Question:- The major products A and B in the following reactions are:

1720600856029


  1. 1720600856074

  2. 1720600854949

  3. 1720600855903

  4. 1720600855239


Answer- 1) 1720600856126

Solution:-

The given reaction occurs as :

\mathrm{R-O-O-R\xrightarrow[]{\Delta}2R\dot{O}}

1720600856280

Therefore, Option(1) is correct.

i didnt have my ews certificate so i filled as general cateogry for jan attemp of jee mains but i am sure i will have it before april attemp so can i refill my cateogry during april registration??

Heya,

Yes, you can refill your category again. In the case of the April session JEE Main registration, you have the option to change your category while registering your details only once. You can switch from General to EWS if you have a proper certificate. Just be certain that the EWS certificate is granted before the last date of the April session form and complies with the NTA's requirements of validity.

Hope it helps!!!

if I got less than 75% 12th boards and got a very good rank in JEE mains like under 1000 then can I get admission in DTU and iiit hyderabad

Hello,

You can certainly get admission at DTU (Delhi Technological University) as the minimum requirement there is 60% aggregate in PCM. In such a case, you will be given admission to the top branches of CSE/ECE. Nevertheless, the case is totally different for IIT Hyderabad.

Admission into IITs is through JEE Advanced, and they require either a minimum of 75% in boards or to be in the top 20th percentile of the board for eligibility. But, if you fail to get 75% and happen to not be in the top 20th percentile, you can't get admission at IIT even if you have a good rank in JEE Mains.

Hope it helps!!!

I am confused bcz I am not prepared for jee january attempt so I thought I will give only april attempt when I completed my whole syllabus is this right for me?

Hello Tanishka,

Although i believe your attempting strategy and sequence depends entirely on your stage of preparation and your personal progress, i would suggest you sit for your January attempt even if you aim to seriously prepare for April.

Whatever stage of syllabus completion you are at, i suggest you give it a try to get an estimate of the exam difficulty and see roughly where you stand among the applicants that year. No matter how many mock tests you attempt, the actual examination environment happens to be very different from mock tests. The first attempt is going to give you an idea of the exam environment so you can prepare for your April attempt better.

All the best for your exams!

jee main registration requires ews certificate application number...the registration will start in last of October 2025 for january 2026 jee mains ..but councelling process will be in july 2026 ..so if i make my ews certificate now ..then will it be valid for 2026 or it. should be made after April 2026 .

Hello Swati

Yes, your EWS certificate will be valid for JEE Main 2026 and counselling if it’s issued after April 1, 2025.
This is because EWS certificates are valid for one financial year from April to March.
So, a certificate made in October 2025 will be for FY 2025–26, which covers both JEE and counselling. You’ll need the certificate number during JEE registration in October 2025.
Even if you don’t have it yet, you can still register and upload it later during counselling. Just make sure the certificate clearly mentions the correct financial year.
Always keep a few extra copies and the original ready for verification.
You're good to go if it’s issued after April 1, 2025
