JEE Main

Full outline

A complete chapter-wise plan for JEE Main built on the current reduced NTA syllabus. Covers the exam pattern and the 2025 marking changes, all 19 Physics units, all 20 Chemistry units and all 14 Mathematics units grouped the way you should actually study them, what was deleted in 2024 so you stop wasting time on it, plus the practice system, revision plan and the road to JoSAA and Advanced.

1. 01Know The Exam

   An afternoon here saves months of studying the wrong things.

   • Pattern & marking scheme

     Paper 1 (B.E./B.Tech) is 75 questions for 300 marks in 3 hours — 25 questions per subject, split 20 MCQ (Section A) and 5 numerical (Section B).

   • The 2025 change most students miss

     Section B used to give you ten numericals to pick five from. That choice is gone, and negative marking now applies there too.

   • Two sessions, best of two

     JEE Main runs in January and April. If you sit both, the better NTA score counts — so session 1 is a free, full-stakes rehearsal.

   • Deleted syllabus — stop studying this

     NTA cut roughly 15% of the syllabus in 2024 and it has stayed out since. Old books and old seniors will still push these at you.

   • Eligibility & attempts

     Know the rules before they cost you a seat at admission time.

   • Percentile, NTA score and rank

     JEE Main reports percentile, not marks. Understanding normalisation stops you panicking over a shift that felt hard.

2. 02Physics · Mechanics

   The base everything else in Physics stands on. Do not rush it.

   • Units, Dimensions & Measurement

     Small chapter, easy marks, and dimensional analysis lets you eliminate wrong options all paper long.

   • Kinematics

     Motion in a straight line and in a plane. Graph-reading questions appear almost every session.

   • Laws of Motion

     Free-body diagrams are the single most transferable skill in Physics. Get ruthless about drawing them.

   • Work, Energy & Power

     Often the fast route through a problem that looks brutal with forces alone.

   • Rotational Motion

     The chapter most students fear and most students under-prepare. It is very learnable, and it is scoring.

   • Gravitation

     Short syllabus, predictable question shapes, reliably 1–2 questions.

   • Properties of Solids & Liquids

     A grab-bag chapter that quietly supplies formula-based marks every year.

3. 03Physics · Heat, Oscillations & Waves

   Compact chapters with a very high marks-per-hour return.

   • Thermodynamics

     Small chapter, consistently 2–3 questions, and it overlaps with Chemistry thermodynamics.

   • Kinetic Theory of Gases

     Formula-driven and quick to master. Regularly 1–2 questions.

   • Oscillations (SHM)

     Recognising SHM in a disguised system is the whole skill here.

   • Waves & Sound

     Standing waves and beats are the recurring favourites.

4. 04Physics · Electrodynamics

   The heaviest-weighted block in Physics. Treat it that way.

   • Electrostatics

     Among the highest-weighted Physics chapters year after year.

   • Current Electricity

     Typically the single most-asked Physics chapter in recent sessions.

   • Magnetic Effects of Current & Magnetism

     Biot–Savart and Ampere's law do most of the work here.

   • EMI & Alternating Current

     Faraday, Lenz, and then the LCR circuit — dependable marks every session.

   • Electromagnetic Waves

     Tiny chapter, almost pure recall, and nearly always worth a question.

5. 05Physics · Optics & Modern

   High return per hour — finish these before the last month.

   • Ray Optics

     Sign conventions cause more lost marks here than concepts do.

   • Wave Optics

     Young's double slit is asked more or less every single session.

   • Dual Nature of Matter & Radiation

     Short, conceptual, and very reliably examined.

   • Atoms & Nuclei

     Bohr's model overlaps directly with Chemistry atomic structure — study them together.

   • Semiconductor Electronic Devices

     Note that transistor topics were pruned in the 2024 revision — confirm the current scope.

   • Experimental Skills

     A dedicated syllabus unit that most candidates skip entirely. Cheap marks.

6. 06Chemistry · Physical

   The calculation half. Mole concept first — everything leans on it.

   • Some Basic Concepts of Chemistry

     The mole concept underpins stoichiometry, solutions, equilibrium and electrochemistry. Weak here means weak everywhere.

   • Atomic Structure

     Overlaps heavily with Physics (Atoms). Learn once, score in two subjects.

   • Chemical Bonding & Molecular Structure

     The highest-value chapter in Chemistry — it feeds directly into both Inorganic and Organic.

   • Chemical Thermodynamics

     Conceptually the same machinery as Physics thermodynamics, applied to reactions.

   • Solutions

     Colligative properties are almost guaranteed to show up.

   • Equilibrium

     Two chapters in one: physical/chemical equilibrium and ionic equilibrium.

   • Redox Reactions & Electrochemistry

     Balancing redox equations is a skill worth drilling until it is automatic.

   • Chemical Kinetics

     Small, formula-driven, and dependable.

7. 07Chemistry · Inorganic

   Four units after the 2024 cuts. Memory-heavy, and the fastest block to finish.

   • Classification of Elements & Periodicity

     Trends explain most of Inorganic. Learn the reasoning, not just the order.

   • p-Block Elements

     The largest Inorganic chapter. Groups 13–18, reactions and compounds.

   • d- and f-Block Elements

     Transition metal behaviour plus lanthanoids and actinoids.

   • Coordination Compounds

     Consistently 2–3 questions, and very learnable in a week.

8. 08Chemistry · Organic

   Mechanism-first. Memorising reactions without GOC does not survive the exam.

   • Purification & Characterisation

     Short unit covering separation methods and quantitative analysis.

   • Basic Principles of Organic Chemistry

     GOC is the master key. Every reaction in every later chapter is an application of what is here.

   • Hydrocarbons

     Alkanes, alkenes, alkynes and aromatics — where mechanisms become concrete.

   • Organic Compounds containing Halogens

     SN1 vs SN2 vs E1 vs E2 is the most examined decision in Organic.

   • Organic Compounds containing Oxygen

     The largest Organic block — alcohols, phenols, ethers, aldehydes, ketones, acids.

   • Organic Compounds containing Nitrogen

     Amines and diazonium salts — a compact, reliably examined block.

   • Biomolecules

     Mostly recall. Note that Polymers and Chemistry in Everyday Life were deleted.

9. 09Maths · Algebra

   With calculus, over half the Mathematics paper.

   • Sets, Relations & Functions

     The vocabulary the rest of the paper is written in.

   • Complex Numbers & Quadratic Equations

     Two closely linked topics, reliably 2–3 questions between them.

   • Matrices & Determinants

     Mechanical and high-yield — among the most consistently asked Maths chapters.

   • Permutations & Combinations

     Short syllabus, deceptively tricky questions. Practice is the only fix.

   • Binomial Theorem

     Very formulaic, and almost always worth a question.

   • Sequences & Series

     AP, GP, HP and standard summations.

10. 10Maths · Calculus

    The single heaviest block in the Mathematics paper.

    • Limits, Continuity & Differentiability

      Feeds every later calculus question. Be fluent, not merely familiar.

    • Integral Calculus

      Indefinite and definite integration, plus area under curves.

    • Differential Equations

      Small chapter, standard forms, near-guaranteed marks.

11. 11Maths · Geometry, Vectors & Probability

    Coordinate geometry alone is worth roughly five questions.

    • Trigonometry

      Identities feed into calculus, complex numbers and coordinate geometry alike.

    • Straight Lines & Circles

      The foundation of the whole coordinate geometry block.

    • Conic Sections

      Parabola, ellipse and hyperbola — usually 2–3 questions.

    • 3D Geometry & Vector Algebra

      Merged and trimmed in the 2024 revision — check the current scope before over-preparing.

    • Statistics & Probability

      Statistics is nearly free marks; probability needs genuine practice.

12. 12The Practice System

    Coverage does not score. Retrieval does.

    • NCERT first, always

      Especially for Chemistry, where questions are lifted almost verbatim from NCERT lines. Finish it before touching a reference book.

    • Previous year questions

      The highest-value material in existence for this exam. PYQs tell you what the syllabus document cannot: what actually gets asked.

    • Mock tests on a schedule

      Three hours of sustained accuracy is a trained skill, separate from knowing the syllabus.

    • Analyse harder than you attempt

      A mock you do not analyse is three hours thrown away. Budget more time for review than for the test.

    • Error log & revision notes

      One notebook per subject, only the things you got wrong. By March it becomes the only thing you need to revise.

    • Speed & attempt strategy

      At roughly 2.4 minutes per question, knowing when to leave one is worth as much as knowing how to solve it.

13. 13Last 60 Days & After

    No new topics. Consolidate, test, and get the admin right.

    • The final revision plan

      The last two months are for retrieval, not for coverage. Starting a brand-new chapter here usually costs more than it returns.

    • Session 1 → Session 2

      The window between sessions is the most valuable month in the whole year. Most people waste it.

    • Exam day protocol

      Remove every variable that isn't the paper.

    • JoSAA counselling

      A great rank badly filled is a wasted rank. This is decided in one afternoon.

    • On to JEE Advanced

      The top ~2.5 lakh Main qualifiers are eligible for Advanced, and it is a genuinely different exam.

    • Not burning out

      This is a two-year exam. The students who peak in October rarely peak in January.
