Hi. The weightage chapters for JEE Mains 2026 batch are expected to be similar to those of 2025. Here are some key chapters and their weightage:

Physics:

- *Modern Physics*: 10% weightage, covering topics like photoelectric effect, Bohr’s model, and dual nature of matter.¹

- *Electrodynamics*: 8% weightage, covering electromagnetic induction and alternating current.

- *Mechanics*: 10% weightage, covering work-energy theorem, rotational motion, and gravitation.

- *Optics*: 6% weightage, covering ray optics and wave optics.

- *Thermodynamics*: 8% weightage, covering laws of thermodynamics and heat transfer.

Mathematics:

- *Calculus*: 12% weightage, covering limits, continuity, differentiation, and integration.

- *Algebra*: 10% weightage, covering complex numbers and quadratic equations.

- *Coordinate Geometry*: 12% weightage, covering circles, conic sections, and straight lines.

- *Probability and Statistics*: 6% weightage, covering Bayes’ theorem, mean, and variance.

- *Trigonometry*: 6% weightage, covering identities, heights, and distances.

Chemistry:

- *Atomic Structure*: 5% weightage, covering quantum numbers, Bohr’s model, and electronic configuration.

- *Chemical Bonding and Molecular Structure*: 7% weightage, covering hybridization, VSEPR theory, and molecular shapes.

- *Thermodynamics and Equilibrium*: 7% weightage, covering pH, solubility equilibrium, and Gibbs free energy.

- *Redox Reaction and Electrochemistry*: 8% weightage, covering Nernst equation and Faraday’s laws.

- *Solutions*: 7% weightage, covering colligative properties, osmosis, and Henry’s Law.

Keep in mind that these weightages are based on the 2025 exam pattern and may be subject to change. It's essential to check the official JEE Mains website for the latest updates on the exam pattern and syllabus.
