The Joint Entrance Examination (JEE) is one of the most challenging and prestigious entrance exams in India for engineering aspirants. As JEE 2025 approaches, understanding the important topics and their weightage can help students plan an effective preparation strategy. The JEE exam is divided into two levels: JEE Main and JEE Advanced. While JEE Main focuses on a broader range of topics, JEE Advanced tests deeper conceptual understanding. In this blog, we will explore the most crucial topics and their chapter-wise weightage for Physics, Chemistry, and Mathematics. At Apollo Academy, we provide structured coaching for JEE Main and JEE Advanced, focusing on high-yield topics, problem-solving techniques, and mock test analysis.
Physics Important Topics & Chapter-Wise Weightage

- Kinetic Theory of Gases
- Heat Transfer
Thermodynamics and Heat-related topics contribute around 10-15% of the exam and often have conceptual as well as numerical problems.
Chemistry Important Topics & Chapter-Wise Weightage
Chemistry is divided into three segments: Physical Chemistry, Organic Chemistry, and Inorganic Chemistry. It is considered a scoring subject if one focuses on NCERT concepts and practices numerical problems well.
- Physical Chemistry (30-35%)
- Some Basic Concepts of Chemistry (Mole Concept)
- Atomic Structure
- Thermodynamics
- Chemical Equilibrium
- Electrochemistry
- Solid State
- Chemical Kinetics
Physical Chemistry occupies 30-35% of the total Chemistry weightage.The numerical questions are based more on formulas and calculations.
- Organic Chemistry (30-35%)
- General Organic Chemistry (GOC)
- Hydrocarbons
- Alcohols, Phenols, and Ethers
- Aldehydes, Ketones, and Carboxylic Acid
Organic Chemistry accounts for a good amount of the exam (30-35%) and requires knowledge of reaction mechanisms, named reactions, and isomerism.
- Inorganic Chemistry (25-30%)
- Chemical Bonding and Molecular Structure
- Coordination Compounds
- P-Block, D-Block, and F-Block Elements
Environmental Chemistry
Metallurgy
Inorganic Chemistry, with its 25-30% weightage, requires students to focus on memorization-based learning and periodic trends
Mathematics Important Topics & Chapter-Wise Weightage
- Mathematics is a high-scoring subject that requires logical thinking and problem-solving ability. The JEE Mathematics syllabus covers a mix of Algebra, Calculus, Trigonometry, and Coordinate Geometry.
- Algebra (30-35%)
- Quadratic Equations
- Complex Numbers
- Binomial Theorem
- Matrices and Determinants
- Probability
Permutations and Combinations
Algebra is one of the most crucial sections in Mathematics, with nearly 30-35% of the questions appearing from this topic. Matrices, Determinants, and Probability are frequently tested.
- Calculus (30-35%)
- Limits and Continuity
- Differentiation
- Application of Derivatives
- Integration and its Applications
Differential Equations
Calculus carries about 30-35% of the Mathematics weightage and is one of the most scoring sections if concepts are well understood.
- Coordinate Geometry (20-25%)
- Straight Lines
- Circles
Conic Sections (Parabola, Ellipse, Hyperbola)
Coordinate Geometry constitutes around 20-25% of total marks and questions are pretty direct yet involve some kind of extensive calculation.
Vector and 3D Geometry: (10-15%)
Vectors
Three-Dimensional Geometry
Vectors and 3D Geometry takes around 10-15% of weightage, but questions in these are easy with right practice.
- Trigonometry (5-10%)
- Trigonometric Identities and Equations
- Heights and Distance
Inverse Trigonometric Functions
Though constituting just around 5-10% questions, trigonometry is the backbone as all of them have to be implemented elsewhere in Math.
Final JEE 2025 Preparation Strategies
Focus on NCERT Books: For Chemistry, NCERT books are crucial, especially for Inorganic Chemistry. Many direct questions come from these textbooks.
Many direct questions come from these textbooks.
- Time Management: Create a timetable focusing on high-weightage chapters while ensuring revision time.
- Mock Tests & Previous Year Papers: Regularly practice JEE Main and Advanced previous year papers and take mock tests to analyze strengths and weaknesses.
- Conceptual Clarity: Understand the concepts and their applications, especially in Physics and Mathematics, rather than rote learning.
- Regular Revision: Keep a formula book and revise regularly to retain key concepts and formulas.
