JEE Main 2026 Syllabus (Physics, Chemistry & Maths) – Latest NTA Pattern

The academic landscape for the JEE Main 2026 syllabus has been refined by the National Testing Agency (NTA) to align more closely with the National Education Policy (NEP) 2020. For students targeting premier engineering institutes in 2026, understanding the syllabus isn't just about a list of chapters; it is about recognizing the stream-specific depth required for B.E., B.Tech, B.Arch, and B.Planning courses.

As we move into 2026, the exam continues to serve as the gateway to diverse academic streams like Civil Engineering, Chemical Engineering, and the rapidly growing B.Sc Data Science. This guide provides a comprehensive breakdown of the syllabus, weightage, and course details you need to master the 2026 session.

JEE Main 2026 Syllabus

1. Physics: The Foundation of Engineering Streams

The Physics section of the JEE Main 2026 syllabus is designed to test conceptual clarity and its application in real-world engineering. For students interested in streams like Civil Engineering or Mechanical Engineering, these topics form the bedrock of their future course curriculum.

Key Physics Topics and 2026 Weightage

Physics is divided into two sections: Section A (Theory) and Section B (Experimental Skills).

Unit	Topic	Approximate Weightage
Modern Physics	Dual Nature of Matter, Atoms & Nuclei	20–25%
Current Electricity	Ohm’s Law, Kirchhoff’s Laws	15–20%
Optics	Ray & Wave Optics	10–12%
Thermodynamics	Laws of Thermodynamics, Heat Engines	8–10%
Mechanics	Laws of Motion, Kinematics, Gravitation	10–12%

Note: NTA has maintained the removal of "Communication Systems" and certain experimental precision topics in the 2026 cycle to streamline the workload for students.

2. Chemistry: Physical, Organic, and Inorganic Specialization

Chemistry is often the most scoring subject in the JEE Main 2026 syllabus. It is categorized into three streams that directly relate to higher studies in Chemical Engineering and Biotechnology.

• Physical Chemistry: Focuses on Chemical Kinetics, Equilibrium, and Thermodynamics.

• Inorganic Chemistry: Covers Coordination Compounds and P-block elements (High weightage in 2026).

• Organic Chemistry: Reaction mechanisms, Biomolecules, and Hydrocarbons.

3. Mathematics: Logical Reasoning & Data Analytics

Mathematics in the JEE Main 2026 syllabus has seen a shift toward "Applied Mathematics" concepts. This is particularly relevant for students aiming for the B.Sc Data Science stream, where Statistics and Probability are paramount.

High-Priority Math Chapters

• Calculus (12–14%): Limits, Continuity, and Differentiability.

• Coordinate Geometry (10–12%): Conic Sections and Straight Lines.

• Probability & Statistics (5–7%): Essential for AI and Data Science aspirants.

• Matrices & Determinants (5–7%): Foundation for computational engineering.

4. Stream Details for B.Arch and B.Planning

The JEE Main 2026 syllabus for Paper 2A (B.Arch) and Paper 2B (B.Plan) shares the Mathematics section with Paper 1 but includes specialized aptitude and drawing modules.

• B.Arch Aptitude: Visualizing 3D objects from 2D drawings, analytical reasoning, and sketching urbanscapes.

• B.Planning Aptitude: General awareness of social sciences, urbanization, and map-reading skills.

5. JEE Main 2026 Exam Pattern & Marking Scheme

To excel in the JEE Main 2026 syllabus, students must adapt to the "Numerical Value Questions" (NVQs) which require precise calculations without options.

• Section A (MCQs): 20 Questions (Compulsory)

• Section B (Numerical): 10 Questions (Only 5 to be attempted)

• Marking: +4 for correct, -1 for incorrect.

Academic Preparation for B.Sc Data Science

Many students use their JEE preparation to pivot into specialized science degrees. In 2026, the B.Sc Data Science stream is integrating "Generative AI" and "Ethical Data Mining" into its first-year curriculum.

Frequently Asked Questions (FAQs)

Q1: Has the JEE Main 2026 syllabus been reduced?

No, there are no additional deletions in the JEE Main 2026 syllabus compared to the 2025 version. The 2024 reductions (like Communication Systems and Mathematical Reasoning) remain in effect.

Q2: Is Mathematics mandatory for B.Sc Data Science in 2026?

Yes, most premier universities require Mathematics or Applied Mathematics as a core subject in the qualifying exam or through the JEE Main 2026 syllabus domain.

Q3: Which subject has the highest weightage in JEE Main Physics?

Modern Physics and Current Electricity consistently hold the highest weightage, accounting for nearly 40% of the Physics section.

Q4: Can I get into B.Sc Data Science through JEE Main scores?

While JEE Main is primarily for B.Tech, some specialized institutes and private universities accept JEE scores for their B.Sc Data Science and AI programs.

Conclusion

The JEE Main 2026 syllabus is more than just a hurdle; it is a comprehensive introduction to the specialized academic streams of the future. Whether you are aiming for a B.Tech in Civil Engineering or a research-heavy B.Sc in Data Science, mastering these topics is your first step toward academic excellence in 2026.
