Oct 27, 2026

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. The official 2027 syllabus is out and is the same as 2026.

Latest update (October 2026): NTA has released the official JEE Main 2027 syllabus PDF along with the Information Bulletin (24–25 October 2026). The syllabus is unchanged from 2026: no chapters or topics have been added or removed. Paper 1 still has 54 units (20 Physics, 20 Chemistry, 14 Maths). Session 1 is on 20–24 and 28 January 2027 and Session 2 is in April 2027.

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

No. NTA has not changed the syllabus. The syllabus was reduced in 2024, and the 2027 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.

Exam Year Syllabus Status What It Means for You
2024 Syllabus reduced (about 25% for Paper 1) Several chapters removed
2025 Reduced syllabus continued No new deletions
2026 Official NTA PDF: 20 Physics, 20 Chemistry, 14 Maths units Same reduced structure
2027 Official NTA PDF: 20 Physics, 20 Chemistry, 14 Maths units  Unchanged from 2026. Prepare from the 2027 PDF

Chapters and Topics Removed from the JEE Main Syllabus

These topics were removed in the 2024 reduction and do not appear in the 2026 or 2027 NTA PDFs.
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 but the 2027 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 2027 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.

JEE Main Paper 1 Marks Distribution

Subject Questions Marks Share of Paper
Physics 25 (20 MCQ + 5 numerical) 100 One-third
Chemistry 25 (20 MCQ + 5 numerical) 100 One-third

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?

Many students search for the "IIT JEE syllabus" and land on the wrong page. "IIT JEE" is a general term that covers two exams, and each has its own syllabus.

Point JEE Main JEE Advanced
Conducted by NTA One of the IITs (rotating organiser)
Used for Admission to NITs, IIITs and GFTIs; qualifying for JEE Advanced Admission to the IITs
Syllabus Reduced NCERT-based list on this page Separate syllabus published at jeeadv.ac.in
Who can appear Class 12 pass or appearing students Only candidates who qualify through JEE Main

For full details on eligibility, dates and the application process, visit our JEE Main 2027 page.

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 on 31 October 2025. The JEE Main 2027 syllabus went online on 24–25 October 2026, 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.
