JEE Main Syllabus 2027: NTA PDF, Chapter-Wise Topics and Weightage

Oct 01, 2026

JEE Main Syllabus 2027: Quick Answer

The JEE Main syllabus 2027 covers Physics, Chemistry and Mathematics based on the NCERT Class 11 and Class 12 curriculum. Paper 1 (B.E./B.Tech) has 75 questions (25 per subject) for 300 marks. Paper 2 (B.Arch/B.Planning) adds Mathematics, an Aptitude Test and a Drawing or Planning test. The syllabus is published only by the National Testing Agency (NTA) at jeemain.nta.nic.in.
 
Latest update (October 2026): NTA has not yet published a separate, new syllabus PDF for JEE Main 2027. The syllabus is expected to stay the same as the JEE Main 2025 syllabus and the 2026 syllabus, with no new chapters added or removed. Students can start preparing now and should check the official NTA PDF once it is released with the information bulletin for the January and April 2027 sessions. This page is updated as soon as that happens.
 
This guide gives you the chapter-wise list for each subject, the topics that were deleted, chapter-wise priority, class-wise split, the Paper 2 syllabus and the steps to download the official PDF. For dates, eligibility and the complete exam overview, see our JEE Main 2027 page.
 

JEE Main Syllabus 2027 PDF Download (NTA Official Link and Steps)

NCERT Class 11 and Class 12 chapters make up the JEE Main syllabus. NTA releases it as a PDF on the official website, usually along with the information bulletin when registration for session 1 opens. For the 2025 cycle this happened around late October 2024, so students can expect a similar timeline for 2027.
 

How to download the JEE Main syllabus PDF:

1.     Go to the official website jeemain.nta.nic.in.
2.     Open the Information Bulletin or the Syllabus section on the home page.
3.     Select the latest JEE Main syllabus for Paper 1 (B.E./B.Tech) or Paper 2 (B.Arch/B.Planning).
4.     Download and save the PDF. NTA also publishes a Hindi version for candidates who want to study in Hindi.
 

Direct Link to the Latest NTA Syllabus

Until the 2027 PDF is released, use the JEE Main 2026 syllabus PDF from NTA. It covers Paper 1, Paper 2A (B.Arch) and Paper 2B (B.Planning).
 

JEE Main Syllabus 2027 vs 2025 and 2026: Is There Any Change?

No major change is expected. The syllabus was reduced in 2024, and the 2026 NTA PDF keeps the same structure of 14 Maths units and 20 units each in Physics and Chemistry. Students searching for the JEE Mains 2025 syllabus or the 2026 syllabus will find that the same chapter list applies to 2027.

Chapters and Topics Removed from the JEE Main Syllabus

These topics were removed in the 2024 reduction and do not appear in the 2026 NTA PDF.
 
Subject
Topics Not in the Current Syllabus
Physics
Communication Systems; some topics from Experimental Skills
Chemistry
States of Matter; Surface Chemistry; Hydrogen; s-Block Elements; General Principles and Processes of Isolation of Metals; Environmental Chemistry; Polymers; Chemistry in Everyday Life
Mathematics
Mathematical Induction; Mathematical Reasoning; Linear Programming; equation of a plane in 3D geometry
 
Note on Capacitors: Many older articles list "Capacitors and Capacitance" as deleted, but the 2026 NTA PDF includes capacitors, their combinations and stored energy inside Unit 11 (Electrostatics). Study it.
 

Paper 1 Marking Pattern

Each subject has 25 questions: 20 multiple-choice questions and 5 numerical-value questions. All five numerical questions in each subject are compulsory (the optional-question choice was removed in 2025). A correct answer earns 4 marks, and incorrect answers carry negative marking, so every subject carries 100 marks.

JEE Main Chapter-Wise Weightage 2027 (Unit-Wise Expected Questions)

NTA does not publish unit-wise weightage, so every weightage table online is an estimate from past papers. Many of them are also outdated: they still show 30 questions per subject (the old pattern) or include chapters that have been deleted. The tables below use the current pattern of 25 questions per subject and only the units in the 2026 NTA syllabus. Treat the ranges as a study-priority guide, not a prediction. A single paper can vary by one or two questions per unit.

How to Use This Weightage Table

  • Cover every unit once. A "Low" unit can still bring a full question and four marks.
  • Revise "High" units first and solve previous year questions from them.
  • In Maths, calculus and co-ordinate geometry together make up a large share of the paper.
  • In Physics and Chemistry, the numerical questions are compulsory, so practise numerical-type problems from every unit.
Our guide on how many questions are there in JEE Mains explains the paper structure in more detail.
 

JEE Main Class 11 and Class 12 Syllabus Split

The "Class" column in the tables above shows where each unit sits. In short, Physics is roughly balanced, Chemistry leans on Class 11 for Physical and basic Organic Chemistry and on Class 12 for advanced Organic and d-block, and Maths has Class 11 algebra and geometry plus Class 12 calculus and vectors.

JEE Main Syllabus 2027 for Paper 2 (B.Arch and B.Planning)

Paper 2 is for admission to B.Arch and B.Planning. Both papers share the same Mathematics and Aptitude Test, then differ in the third part. The Mathematics part uses the same 14 units as Paper 1 (Sets, Relations and Functions to Trigonometry), with no Mathematical Induction or Mathematical Reasoning.

Paper 2A: B.Arch Syllabus

Part I: Mathematics

Same 14 units as Paper 1 Mathematics (see the Maths table above).
 

Part II: Aptitude Test

  • Unit 1: Awareness of persons, buildings, materials, objects and textures related to architecture; visualising 3D objects from 2D drawings and their different sides; analytical reasoning and mental ability (visual, numerical and verbal).
  • Unit 2: Three-dimensional perception: scale and proportion, building forms, colour, texture, harmony and contrast; drawing geometrical or abstract patterns in pencil; transformation of forms in 2D and 3D; plans, elevations and 3D views; creating compositions from given shapes.

Part III: Drawing Test

Sketching scenes and activities from memory, such as urban scenes (public spaces, markets, festivals, street scenes, monuments), landscapes (riverfronts, gardens, trees) and rural life, on a drawing sheet. Candidates should bring pencils, their own geometry box, erasers, colour pencils and crayons.
 

Paper 2B: B.Planning Syllabus

Part I: Mathematics and Part II: Aptitude Test

Same as Paper 2A.
 

Part III: Planning

  • General Awareness: general knowledge about prominent cities, development issues and government programmes.
  • Social Sciences: nationalism, colonialism and colonial cities, resources and development, agriculture, industries, human settlements, federalism, democracy, the Constitution of India, economic development, poverty, urbanisation and rural development.
  • Thinking Skills: comprehension of an unseen passage, map reading, critical reasoning, charts, graphs and tables, and basic statistics and quantitative reasoning.
 

JEE Main vs JEE Advanced vs IIT JEE Syllabus: What Is the Difference?

When Is the JEE Main Syllabus Released? Session-Wise Timing

NTA conducts JEE Main twice a year, in a January session (session 1) and an April session (session 2). One syllabus applies to both sessions. The 2026 syllabus went online in October 2025, and the JEE Main 2027 syllabus is expected around the same time of year, along with the information bulletin. Check our JEE Main exam dates page for the confirmed schedule, and use the JEE Main admit card page when the exam gets closer.
 

How to Use the JEE Main Syllabus for Your Preparation

  • Print the syllabus and tick off each unit as you finish it.
  • Study from NCERT first, then move to problem-solving books for Physics and Maths.
  • Do not study deleted chapters, such as Mathematical Induction or s-Block Elements.
  • Solve previous year papers to see how the high-priority chapters are tested.
  • Revise in cycles and keep the last month for mock tests.
If you are short on time, read our guide on whether you can clear JEE Mains in 6 months for a realistic plan.
