Which are Most Crucial Chapters for JEE Main Physics 2026?
For Physics, high-weightage chapters that ensure maximum scoring potential should be emphasized by students. Physics is numerical-based and concept-driven, so accuracy and speed can be enhanced by understanding key topics.
High-weightage Topics
-
Thermodynamics: Includes kinetic theory, calorimetry, heat transfer, and thermal expansion. High probability of questions; requires conceptual clarity.
-
Optics: A long chapter but highly rewarding. Focus on reflection, refraction, and lens formula for scoring potential.
-
Modern Physics: Covers nuclear physics, photoelectric effect, and atomic models; consistently appears in both Main and Advanced exams.
-
Electrostatics: Must be covered completely. It is often tested through conceptual and numerical problems.
-
Current Electricity and Magnetic Effects of Current: Key numerical-based chapter; forms a core scoring section.
Quick Scoring Topics (Small but Big Impact)
-
Units and Dimensions
-
Wave Optics and Electromagnetic Waves
-
Semiconductors
-
Work, Power, and Energy (Mechanics)
Focusing on these chapters can help cover 60–70% of the Physics section with efficient revision and smart question practice.

Mathematics demands chapter prioritization with regular question trends and firm conceptual clarity. Students should practice daily along with theory revision to enhance speed and accuracy.
High-weightage and Consistent Topics
-
Sequence and Series: Appears in almost every shift, focus on arithmetic and geometric progressions.
-
Determinants and Matrices: Includes Cramer’s rule, inverse matrices, and properties; highly scoring.
-
Binomial Theorem: Frequently tested; revise properties and expansions thoroughly.
-
Vectors and 3D Geometry: Covers shortest distance, vector products, and plane equations; consistently asked.
-
Coordinate Geometry: Straight lines, circles, parabolas, ellipses, and hyperbolas. Around 4–5 questions come per shift.
-
Quadratic Equations and Complex Numbers: Focus on real roots and imaginary numbers.
-
Probability, Permutations & Combinations, and Statistics: Regularly tested numericals.
-
Limits, Continuity, Differentiability, and Differentiation Methods: Important calculus topics for easy scoring.
-
Differential Equations: Commonly tested, especially basic order and degree problems.
-
Integration, Area under Curves, and Trigonometry: Carry moderate weight but are vital for complete coverage.
Consistent practice of these chapters builds confidence and ensures coverage of nearly 70% of the Mathematics section effectively.

Chemistry has one of highest scoring opportunities in JEE Main if prepared smartly. Concept clarity and formula memorisation needs to be balanced. NCERT-based questions and conceptual understanding should be emphasised by the students in Physical, Organic, and Inorganic branches.
Physical Chemistry
- Basic Concepts of Chemistry including stoichiometry, limiting reagents, and concentration terms.
- Thermodynamics and Thermochemistry with focus on thermochemical equations and easy numerical problems.
- Solutions with focus on abnormal molar mass and colligative properties.
- Chemical and Ionic Equilibrium, particularly pH and solubility product problems.
Organic Chemistry
- General Organic Chemistry including purification, characterization, and reaction mechanisms.
- Aldehydes, Ketones, and Carboxylic Acids focusing on Aldol and Cannizzaro reactions.
- Haloalkanes and Haloarenes with emphasis on isomerism and substitution reactions.
Inorganic Chemistry
- Coordination Compounds covering hybridization, magnetic behavior, and isomerism.
- D-block and F-block Elements with focus on electronic configurations and reactions.
- Chemical Periodicity including classification of elements, periodic trends, and oxidation states.
Adding a mix of conceptual and numerical practice from these areas allows students to manage time effectively while improving accuracy in Chemistry.
