Important Chapters for JEE PCM – Last-Minute Revision Guide
As the JEE Main and Advanced exams approach, smart revision becomes more important than extensive study. At this stage, focusing on high-weightage, formula-driven, and frequently asked chapters can significantly improve accuracy and overall score.
This page provides a subject-wise list of the most important chapters in Physics, Chemistry, and Mathematics, specially curated for last-minute revision.
Physics – High-Scoring & Repeated Chapters
Physics questions in JEE often test concept clarity and formula application. Prioritize the following chapters:
🔹 Mechanics (Core Foundation)
Units & Dimensions
Kinematics
Laws of Motion
Work, Energy & Power
Centre of Mass & Rotational Motion
Gravitation
🔹 Modern Physics (Very High Weightage)
Dual Nature of Matter & Radiation
Atoms
Nuclei
Semiconductor Electronics
🔹 Electricity & Magnetism
Electrostatics
Current Electricity
Capacitors
Magnetic Effects of Current
Electromagnetic Induction
Alternating Current
🔹 Optics & Waves
Ray Optics
Wave Optics
Oscillations & Waves
Last-Minute Tip (Physics):
Revise formulas, dimensional checks, standard graphs, and common numerical models. Avoid learning new derivations now.
Chemistry – Maximum Return with Smart Coverage
Chemistry is the most scoring subject if revised strategically.
🔹 Physical Chemistry (Formula & Numericals)
Mole Concept
Atomic Structure
Chemical Bonding
Thermodynamics
Chemical Equilibrium
Ionic Equilibrium
Electrochemistry
Chemical Kinetics
Solutions

🔹 Organic Chemistry (Reaction-Based)
General Organic Chemistry (GOC)
Isomerism
Hydrocarbons
Haloalkanes & Haloarenes
Alcohols, Phenols & Ethers
Aldehydes, Ketones & Carboxylic Acids
Amines
Focus: Reaction mechanisms, named reactions, reagents, and conversion logic.
🔹 Inorganic Chemistry (NCERT is Key)
Periodic Table & Periodicity
Chemical Bonding
Coordination Compounds
p-Block Elements
d-Block & f-Block Elements
Metallurgy
Focus: NCERT lines, trends, exceptions, and factual data.
Mathematics – Scoring Chapters for Quick Revision
Mathematics requires speed, accuracy, and formula recall.
🔹 Algebra (Very High Weightage)
Quadratic Equations
Sequences & Series
Permutations & Combinations
Binomial Theorem
Complex Numbers
Matrices & Determinants
🔹 Calculus (Rank-Deciding)
Limits, Continuity & Differentiability
Differentiation
Application of Derivatives
Indefinite & Definite Integrals
Differential Equations
Area Under Curves
🔹 Coordinate Geometry

Last-Minute Tip (Maths):
Revise formulas, standard results, shortcut methods, and attempt previous year questions only.
Smart Last-Minute Revision Strategy
Focus on accuracy over attempt count
Revise NCERT (especially Chemistry)
Solve previous year JEE questions
Avoid new chapters or advanced problems
Maintain calm, sleep well, and stay confident
Final Note
JEE is not about knowing everything—it’s about executing what you already know with precision. A focused revision of these important PCM chapters can make a decisive difference in your final score.
