JEE Main 2026 Registration Expected Soon: Check Tentative Chapter-Wise Weightage for Physics, Chemistry and Mathematics
New Delhi, October 2025: The National Testing Agency (NTA) is gearing up to commence the registration process for the Joint Entrance Examination (JEE) Main 2026. Aspirants across the country are awaiting the official notification, which is expected to be released soon on the official website — jeemain.nta.nic.in.
While the exact registration dates have not yet been officially announced, NTA has already activated a demo registration link on its portal to help students familiarize themselves with the online application process. The demonstration link, available at demo.nta.nic.in, allows candidates to practice filling the form before the official registration window opens.
According to reports from The Times of India and The Economic Times, the official JEE Main 2026 registration window is likely to open in November 2025, with the first session of the examination expected to take place in January 2026, followed by the second session around April 2026. Candidates are advised to keep their essential documents, such as Aadhaar card, category certificates, and recent photographs, ready for smooth registration once the portal goes live.
Tentative Chapter-Wise Weightage for JEE Main 2026
With the registration process approaching, aspirants are increasingly focusing on strategic preparation. Analyzing chapter-wise weightage from previous years can help students prioritize topics that carry higher marks potential. Based on the analysis of past JEE Main sessions, here’s a subject-wise tentative weightage distribution for Physics, Chemistry, and Mathematics.
Physics Chapter-Wise Weightage (Tentative)
Physics in JEE Main tests both conceptual clarity and problem-solving speed. Topics like Modern Physics and Electrostatics have consistently carried higher marks in recent sessions.
| Chapter / Topic | Approximate Questions | Weightage (%) |
|---|---|---|
| Modern Physics (Dual Nature, Nuclear Physics, Photoelectric Effect) | 5 | 10–12% |
| Thermodynamics & Kinetic Theory | 3 | 8–10% |
| Current Electricity & Circuits | 3 | 8–10% |
| Electrostatics | 3 | 8–10% |
| Optics (Ray & Wave) | 3 | 8–10% |
| Magnetism & Moving Charges | 2 | 5–6% |
| Mechanics (Kinematics, Rotation, Work & Energy) | 4–5 | 12–15% |
| Waves, SHM, Fluids, Gravitation | 2–3 | 5–6% |
Experts suggest that Modern Physics, Current Electricity, and Electrostatics remain high-scoring areas that students should prioritize. Additionally, conceptual topics such as Thermodynamics and Optics often feature tricky numerical questions that test understanding rather than memorization.
Chemistry Chapter-Wise Weightage (Tentative)
Chemistry continues to be the most scoring section for many aspirants, with a balanced mix of theoretical and conceptual questions. The paper generally includes equal representation from Physical, Organic, and Inorganic Chemistry.
| Chapter / Topic | Weightage (%) | Remarks |
|---|---|---|
| Coordination Compounds | 9–10% | High-weight inorganic topic |
| Periodic Table & p/d/f Block Elements | 9–10% | Frequently asked |
| Chemical Bonding & Molecular Structure | 6–7% | Concept-based |
| Thermodynamics & Gaseous State | 6–7% | Numerical-heavy |
| Atomic Structure | 6–7% | Fundamental chapter |
| Solid State & Surface Chemistry | 6% | Moderate importance |
| Chemical & Ionic Equilibrium | 6% | Conceptually important |
| Electrochemistry, Kinetics, Solutions, Redox | 3–5% each | Lower but relevant |
| Organic Chemistry (Hydrocarbons, Biomolecules, Reactions) | 10–12% | High-yield for strong conceptual learners |
Teachers recommend mastering Coordination Compounds, Chemical Bonding, and Thermodynamics, as these topics often contribute multiple questions. Organic Chemistry, though unpredictable, can be mastered through consistent practice and understanding of reaction mechanisms.
Mathematics Chapter-Wise Weightage (Tentative)
Mathematics in JEE Main focuses on problem-solving efficiency and conceptual application. Calculus and Coordinate Geometry remain dominant areas.
| Chapter / Topic | Weightage (%) | Remarks |
|---|---|---|
| Calculus (Limits, Differentiation, Integration) | 12–14% | Most important |
| Coordinate Geometry | 10–12% | High frequency |
| Conic Sections (Parabola, Ellipse, Hyperbola) | 10% | Repeatedly asked |
| 3D Geometry & Vectors | 6–8% | Moderate to high weight |
| Matrices & Determinants | 6–7% | Frequently asked |
| Probability & Statistics | 5–6% | Moderate |
| Sequence & Series | 4–5% | Consistent |
| Complex Numbers & Quadratic Equations | 4–5% | Important |
| Trigonometry, Binomial Theorem, Relations & Functions | 3–4% each | Lower but necessary for full coverage |
Experts highlight Calculus and Coordinate Geometry as the two pillars of JEE Main Mathematics. These chapters, if practiced thoroughly, can contribute nearly one-fourth of the total marks in the Mathematics paper.
Preparation Strategy Based on Chapter Weightage
Prioritize High-Weight Chapters: Start with topics that appear most frequently — Modern Physics, Electrostatics, Thermodynamics, Chemical Bonding, Coordination Compounds, Calculus, and Coordinate Geometry.
Focus on Conceptual Understanding: Questions in JEE Main often test application over rote learning, especially in Physics and Mathematics.
Revise with PYQs (Previous Year Questions): Solving past papers helps identify recurring question patterns and improves time management.
Balanced Coverage: While high-weight topics deserve more focus, neglecting smaller chapters can be risky as they may contribute easy-scoring questions.
Mock Tests and Analysis: Regular mock tests under timed conditions help build confidence and reduce exam-day anxiety.
What’s Next for JEE Main 2026 Aspirants
Candidates are advised to monitor the NTA’s official website regularly for the release of the JEE Main 2026 Information Bulletin, which will confirm key dates for registration, correction window, admit cards, and examination sessions.
Once the registration opens, aspirants should carefully read the guidelines, verify details before submission, and retain a printed copy of the confirmation page for future reference.
For continuous updates on JEE Main 2026, candidates can follow reputable education portals such as Careers360, Collegedunia, and Times of India Education.
In summary:
Registration likely: November 2025
Session 1 exam window: January 2026
Session 2 exam window: April 2026
Weightage focus: Modern Physics, Coordination Compounds, Calculus, Coordinate Geometry
With only a few months left for the exam, focused preparation and smart strategy based on topic-wise trends can significantly boost performance. Students are encouraged to keep their documents ready, monitor official announcements, and continue consistent, structured study to maximize their chances in JEE Main 2026.
