JEE Main Physics syllabus 2026
Aspirants preparing for JEE Main 2026 won’t have an officially released Physics syllabus just yet, but they can safely refer to the JEE Main 2025 Physics syllabus as a reliable guide for now.
The National Testing Agency (NTA) has made the JEE Main 2025 syllabus available in PDF format. By reviewing the full document, students can establish a solid, organized study plan. Notably, the JEE Main 2025 syllabus is identical to that of the previous year, so it remains fully relevant.
In the last jee main syllabus revision, there were a few topics that were deleted from Physics, Chemistry, and Mathematics. Of particular mention is in the Physics part—namely in the chapter Kinematics—where there were some changes. Very important concepts like Scalars and Vectors were cut out from the JEE Main 2025 syllabus.
For Physics, approximately 50–55% of the questions generally arise from Class 11 subjects, mainly dealing with Mechanics and Waves. The rest, i.e., 45–50%, are based on Class 12 subjects, with emphasis on electrodynamics and Modern Physics.
JEE Main Physics Syllabus 2026 Overview
The National Testing Agency (NTA) has not yet released the official Physics syllabus for JEE Main 2026. Like previous years, the syllabus will follow the NCERT curriculum for Classes 11 and 12 and will be split into two parts:
- Section A — theoretical concepts, which make up approximately 80% of the exam
- Section B — practical and experimental topics, accounting for the remaining 20%
Until the 2026 syllabus is published, candidates are advised to follow the JEE Main 2025 Physics syllabus as a reliable reference.

JEE Main Physics Preparation Tips 2026
Strong JEE Main Physics performance hinges on clear conceptual understanding, focused practice, and smart strategies. Begin with a solid grasp of fundamentals—mechanics, thermodynamics, electricity, and optics—since a deep conceptual base simplifies solving complex problems later.
- Prioritize high-impact topics like mechanics, electrostatics, current electricity, and optics, which regularly yield high scores in the exam.
- Reinforce learning through active problem-solving: use NCERT texts, past JEE Main papers, and quality reference books such as H.C. Verma and D.C. Pandey to build fluency .
- Instead of rote memorization, understand why formulas work, so you can apply them flexibly to varied problems . Sharpen your time management by regularly taking timed mock tests, analyzing performance to improve both speed and accuracy.
- Maintain retention with spaced revision of key formulas, derivations, and concepts, using formula sheets or flashcards for periodic review .
Finally, cultivate a positive, resilient mindset—stay disciplined, manage stress, trust your preparation, and balance work with short breaks like meditation or family time .
JEE Main Physics Syllabus 2026 FAQs
No—the NTA has not officially published it yet. As of now, it is expected to align closely with the 2025 syllabus, which draws heavily from NCERT Class 11 and 12 topics.
The syllabus is split into two sections:
- Section A (Theory): Covers core theoretical topics—about 80% of the Physics paper.
- Section B (Practical/Experimental skills): Includes lab-based concepts like measurements and instrument use, making up roughly the remaining 20% .
Yes—about 20% of questions test practical understanding, including instrument usage like Vernier calipers, screw gauge, meter scale, plotting characteristic curves, and resistance measurements .
Changes are rare. The 2025 syllabus mirrored 2024’s with minor adjustments (e.g. some optics and experimental topics removed), Expect the 2026 syllabus to remain largely consistent, with official confirmation pending.
Occasionally, NTA includes challenging or application-based questions that test deeper conceptual understanding—not necessarily out of syllabus, but rather more complex twists on familiar topics .
