JEE Main Physics Syllabus PDF with Chapter-wise Weightage 2026

JEE Main Physics Syllabus with Chapter-wise Weightage 2026: The JEE Main Physics Syllabus 2026 is designed to test candidates on fundamental concepts, application-based problem-solving, and logical reasoning across major Physics domains. The JEE Main Physics Syllabus available here is as per the previous year’s JEE Main official syllabus.  The syllabus includes Mechanics, Electricity, Magnetism, Optics, Modern Physics, and Thermodynamics, ensuring students build strong conceptual clarity. As Physics in JEE Main is known for its balanced mix of theory and numerical questions, understanding chapter-wise weightage becomes essential. High-weightage chapters demand deeper practice, while low-to-moderate weightage topics can yield quick, scoring opportunities. With a smart approach, consistent practice, and a clear understanding of the syllabus structure, aspirants can significantly improve their performance.
