JEE Main Chapter Wise Weightage Last 5 Years

Introduction

JEE Main is the primary entrance exam for admission to NITs, IIITs, and GFTIs. Every year, more than 10 lakh students appear for the exam, making competition intense. This page presents a chapter-wise weightage analysis based on the last five years of JEE Main papers (2021–2025) and explains how students can use these trends to plan their preparation effectively.

In today’s competitive era, it is important to understand exam patterns, identify high-weightage chapters, and allocate your preparation time accordingly. Strategic preparation is the real game changer. That’s exactly what this blog helps you do.

This blog offers a detailed subject-wise, class-wise, and chapter-wise analysis of the last five years of JEE Main papers (2021–2025), including:

• Average number of questions asked per chapter
• Class-wise contribution to the paper
• ROI (Return on Investment): Questions per hour of preparation
• Smart strategy for preparation and revision

With subject-specific insights for Physics, Chemistry, and Mathematics, we break down chapter trends, question frequency, and suggested time allocation for both learning and revision. By the end, you’ll be able to prioritize high-yield chapters, manage your study hours wisely, and avoid common prep mistakes all backed by real exam data.

1. Subject-Wise Overview of JEE Main

JEE Main includes 75 questions (25 from each subject). Out of 25 Questions 20 are MCQ-based and 5 questions are of Numerical Value Type. Each subject contributes equally in terms of marks. However, the level of conceptual depth, numerical solving, and trickiness varies across subjects.

Subject	Class 11	Class 12	Total Ques.	Difficulty Trend
Physics	12	13	25	Concept-heavy, Moderate
Chemistry	10	15	25	Memory + Concept-mix
Mathematics	11	14	25	Lengthy, Tough, Calculation-based

Class-wise Weightage Overview (2021–2025)
based on the average frequency of questions from Class 11 and 12

Insight: While Class 12 chapters show slightly higher question count in Physics, Class 11 remains dominant in Chemistry, and for Mathematics, it stays nearly balanced across both classes.

Subject-wise Level of Difficulty (2021 to 2025)

Over the last five years (2021–2025), the difficulty levels of jee advanced syllabus have shown interesting patterns. Physics has remained moderately consistent with a slight dip in 2025. Chemistry has generally been student-friendly, except for a tougher shift in 2025. Mathematics has consistently been the most challenging subject, with fluctuating but overall high difficulty. Based on this trend, it is advisable for students to focus on building strong conceptual clarity in Physics, prioritize NCERT and revision in Chemistry, and invest more time in practicing lengthy, calculation-heavy questions in Mathematics. Smart planning with subject-specific strategies can help to navigate the paper more effectively and boost scores.

Subjects	2021	2022	2023	2024	2025	Avg.
Physics	3	2	2.2	2.3	2.1	2.32
Chemistry	2	2	1.8	2	3	2.16
Mathematics	2.2	3	2	2.5	2.4	2.42

      (1- Easy, 2- Moderate, 3- Tough) 

2. Physics: A Balanced Mix of Concept & Time Strategy for JEE Main

Physics in the JEE Main is often perceived as a blend of logic, concepts, and calculations, and data from the last five years (2021 to 2025) confirms this. With an average of 30 questions every year, Physics has shown a moderate difficulty level (Average: 2.32 out of 3), meaning it’s neither too easy nor overly tough, but requires smart conceptual clarity.

Class 12 slightly dominates the paper with 56% weightage, but Class 11 isn’t far behind. Chapters such as Current Electricity, Rotational Motion, Kinetic Theory of Gases, and Moving Charges & Magnetism have emerged as high-weightage, high-ROI areas, contributing more than 20 questions over five years.

However, not all chapters are equal. Some, like Relative Motion or Thermal Expansion, carry fewer questions, but they still form the foundation of bigger concepts. Preparation should be time-optimized – focus more time (almost 15 – 19 hours) on chapters with high frequency and tougher understanding, while allotting revision hours smartly (approx. 3–7 hrs) based on question trends.

MyExams Tip: Prioritize chapters with both high frequency and high conceptual demand. Solve PYQs topic-wise to identify patterns and avoid traps. Don’t ignore the NCERT for theory, especially for scoring in conceptual MCQs.

Overall, strategic planning, supported by real data, gives you the edge, not just hard work alone.

Class 11 and 12: Chapters to Prioritize in Physics: Based on 5-year trends, here is the class-wise breakdown:

Physics: ROI-Based Preparation Strategy

• Start with high-ROI chapters that consistently offer more questions for less prep time.
• Avoid time-draining chapters unless you have completed high-return ones; aim for maximum score with minimum effort.
• Regularly revisit the ROI trend to update your strategy based on changing weightage and evolving paper patterns.

3. Chemistry: Trends & Focused Strategy Backed by Data

Chemistry, often viewed as the most scoring subject in JEE Main, offers a perfect balance between theory and application, provided students approach it with the right strategy. A mix of right theory, NCERT facts, and concept application defines this section. A close look at the last five years of JEE Main papers (2021–2025) reveals that Chemistry maintains a nearly even distribution between Class 11 and Class 12 chapters. The weightage, however, slightly tilts in favour of Class 12, especially in Organic and Physical Chemistry.

From a preparation point of view, chapters like Chemical Bonding, Coordination Compounds, Thermodynamics, and Redox Reactions consistently show high question frequency and offer strong Return on Investment (ROI) in terms of questions per hour of preparation. On the other hand, lengthy chapters such as Organic Chemistry – Reaction Mechanism demand deeper conceptual clarity and revision cycles.

What makes Chemistry unique is its mixed nature; some chapters are fact-based (good for quick scoring), while others are concept-heavy (ideal for application-based questions). Our data also show that Chemistry has had the lowest average difficulty level (2.16) among all three subjects.

MyExams Tip: Focus first on high-ROI chapters, especially from Class 12. Build a strong foundation in NCERT concepts, revise regularly, and solve previous year papers. With the right topic prioritization, Chemistry can easily become your scoring anchor in the JEE Main journey.

Class 11 and 12: Chapters to Prioritize in Chemistry: Based on 5-year trends, here is the class-wise breakdown:

Chemistry: ROI-Based Preparation Strategy

• Distribute your prep hours wisely avoid spending too much time on low-ROI chapters, especially in the final prep phase.
• Follow the 60:30:10 rule 60% time on high-ROI chapters, 30% on average ones, and 10% only if time allows for lesser-return topics.
• Reinforce through quick-revision tables, PYQs, and flashcards a high-ROI strategy doesn’t just depend on what you study, but how you revise.

4. Mathematics: Accuracy, Speed & Smart Topic Selection

Maths is lengthy and demands both accuracy and speed. Time management and mastery over formula-based applications are key.

Mathematics often emerges as the most challenging subject in JEE Main, not necessarily due to complex concepts, but because of the lengthy calculations and time pressure. Analysing the past five years of paper trends (2021–2025), we find that Mathematics has maintained the highest average difficulty level (2.42) among all three subjects.

However, smart preparation can drastically improve outcomes. Our data show that chapters like Relation, Binomial Theorem, 3D Geometry, and Area Under Curve deliver high ROI (over 3 questions per hour of prep). This means with less effort, students can gain more marks, a goldmine for those short on time. Chapters such as Definite Integration, Differential Equations, Determinants, and Statistics also feature in the top 10 list of ROI, and have consistently appeared in past papers. Conversely, topics such as Complex Numbers, Matrices, and Coordinate Geometry require longer preparation time but are essential for in-depth concept mastery and problem-solving techniques.

MyExams Tip: Start with high-ROI chapters to build confidence and momentum. Practice mock tests regularly to build speed and accuracy under time pressure. Focus on formula retention and shortcut techniques to reduce silly mistakes. With the right planning, Mathematics can shift from being a feared subject to your highest-scoring one.
