Covering the syllabus is not enough to crack JEE Main 2026; you need to know where to focus. Some chapters are heavier and are more exam-focused, offering better scoring opportunities. Strategic revision at the end of each chapter and practice from trusted JEE Main Chapterwise Books can help you score maximum.
This post details the most scoring chapters of Physics/ Chemistry/ Mathematics and explains how books like Oswaal’s can play an important role in enhancing your preparation.
Physics: Chapters with Maximum Returns
Physics pays back for clear concepts and logical thinking. Some of the chapters are the heart of the question paper for the given year and are quite crucial in getting the score above the cutoff.
🔹 Modern Physics
Modern Physics is frequently the highest-scoring unit, with the unit accounting for 3–4 direct questions in almost every JEE Main paper.
Topics include Photoelectric Effect, Nuclear Physics, Bohr’s Model, etc.
It is a time-effective way to have a Q direct formula based-question.
Identify common question patterns with the JEE Main Chapter-wise and Topic-wise PYQ Book.
🔹 Current Electricity
Frequently features numerical problems on Ohm’s Law, Kirchhoff’s Laws, and resistors in circuits.
-
Appears almost every year with 2–3 questions.
-
Focus on solving problems, not just reading theory.
-
PYQ-based practice helps reinforce tricky concepts with previous years’ trendlines.
🔹 Electrostatics & Capacitance
This chapter is heavily conceptual with predictable question types based on electric field, potential, and capacitors.
-
Use concept boosters for diagram-based questions.
-
Helps in mastering 1–2 high-weightage questions quickly.
🔹 Work, Power & Energy + Laws of Motion
Many questions form the foundation are mainly conceptual and numerical, and they appear together in chapters.
-
Clear your basics for a perfect score.
-
Use the latest Books to practice mind maps and clear your visual concepts for confidence.
Chemistry: Scoring Made Simple
Chemistry is generally seen as the easiest subject to score in because of the combination of factual and conceptual questions. JEE Mains PYQ Chapterwise Chemistry Book helps you to find out the most ‘ASKED’ & ‘IMPORTANT’ ones with a chapter to revise quickly.
🔹 Coordination Compounds
-
This chapter has uniform mark weightage in the JEE Main paper.
-
Includes IUPAC nomenclature, isomerism, and bonding theories.
-
Oswaal’s chapter-wise solved papers are used to identify the frequently asked MCQ types.
🔹 Thermodynamics
Physical chemistry concepts/thermodynamics is still one of top top-scoring chapters, depending on how the numerical practice was done dryly.
Acquaint with the master first law, enthalpy change, and spontaneity criteria.
Oswaal's revision notes, formula sheets dot the i’s and cross the t’s on vivid equations in no time.
🔹 Organic Chemistry – GOC and Named Reactions
From SN1/SN2 to Aldol and Cannizzaro, this is the "go-to" chapter for 3–4 "meat and potatoes" questions.
Plots and reaction mechanisms are useful to visualize the complex networks.
Prepare yourself through topic-wise MCQs & Mock tests of the question bank.
🔹 Chemical Bonding and Molecular Structure
-
Anticipate questions on hybridization, VSEPR theory and molecular orbital diagrams.
-
Mnemonic Devices help with the recall of periodic trends and also structures.
Bonus Tip: Don’t skip Biomolecules. It does tend to have 1 direct question that’s purely theory-based.

Mathematics: Practice-Heavy but Rewarding
-
Maths is all about regular practice; however, even within maths, you can focus on those chapters that will bring you maximum questions with JEE Main Chapterwise Books
🔹 Coordinate Geometry
A high-scoring chapter with straight lines, conic sections, and a pair of lines.
-
Known for 3–4 diagram-based or formula-based questions.
-
Oswaal’s quick concept review and last-minute formula lists make it easier to revise.
🔹 Calculus (Differentiation & Integration)
A pillar of JEE Mathematics, you can expect 4–5 questions from this section.
-
Includes limits, continuity, application of derivatives, and definite integrals.
-
To identify formula-based shortcuts for topics, use pyqs to improve accuracy.
🔹 Probability & Statistics
This is probably favorite chapter in the syllabus - even though physics is so easy, this feels like the icing, the treat at the end of all the hard work!
Questions are largely formulaic and featured virtually every year.
Oswaal’s Concept Videos and formula guides take the stress out of the dummy run.
🔹 Sequence & Series Binomial Theorem
These are concept-loaded but formula-cheering when you see the formulas.
Oswaal QR Codes are linked to the relevant topic to enable further self-study by students.

FAQs
Q1. How do I identify the most important chapters for JEE Main 2026?
You will be able to analyze chapter-wise trends with the help of the Oswaal JEE Mains PYQ Chapterwise Book, which segregates previous year questions as per the chapters. This enables you to concentrate on the high-weightage chapters, which are repeated in the paper.
Q2. Is it okay to skip low-weightage chapters if I'm short on time?
Yes, if basics are strong and you have already completed high-scoring chapters, then you can downvote chapters which has low frequency, like ECh or SCD. Ideally full-length for complete coverage, if time allows.
Q3. Are JEE Main Books enough for scoring 90+ marks?
Yes, Oswaal’s JEE Main Chapterwise Books provide PYQs, Revision tools, concept videos, and mock tests under one roof. If used regularly, particularly with some of your more important chapters, they should be more than enough to pull off a 90+.
