High Weightage Chapters for JEE Main Physics 2027: Chapter-wise Weightage

For JEE Main Physics 2027, students can prioritise chapters that have shown higher question frequency in previous JEE Main sessions. Ray Optics, Rotational Motion, Electric Charges and Fields, Fluid Mechanics, Moving Charges and Magnetism, Thermodynamics, and Electrostatic Potential and Capacitance are among the key chapters highlighted by the available question trends.

The JEE Main Physics chapter-wise weightage can vary across shifts and sessions, so it should be used to plan revision rather than predict the exact number of questions in JEE Main 2027. Students should also cover both Class 11 and Class 12 Physics and practise previous-year questions from important chapters.

JEE Main Physics Chapter-wise Weightage 2027

The table below shows the number of questions recorded from different Physics chapters in the January and April 2025 JEE Main sessions. This historical data can help students identify chapters that appeared frequently in previous sessions.

The number of questions can vary between shifts and sessions, so the data should be used as a preparation reference rather than a fixed prediction for JEE Main 2027.

High Weightage Chapters for JEE Main Physics 2027

Based on the historical question trends shown above, students can give particular attention to:

• Ray Optics and Optical Instruments
• Rotational Motion
• Electric Charges and Fields
• Fluid Mechanics
• Moving Charges and Magnetism
• Thermodynamics
• Electrostatic Potential and Capacitance
• Wave Optics
• Dual Nature of Radiation and Matter
• Semiconductor Electronics
• Current Electricity

These chapters should be prioritised for revision, but students should not completely skip other chapters because question distribution can change across JEE Main shifts.

Important Physics Chapters for JEE Main
