Preparing for JEE Main 2025 is both a marathon and a sprint. With a vast syllabus and increasing competition, every aspirant needs to work smart—not just hard. One proven strategy to maximize your score is to focus on high-weightage chapters that are consistently asked in the exam. These are popularly known as the “Do or Die” chapters—topics that can make or break your performance.
Below is a subject-wise breakdown of the most important chapters you must prioritize.
🔬 Physics: High-Impact Chapters
Physics can be tricky, but focusing on the right areas can give you a strong advantage. Master these crucial topics to boost your marks:
- Electrostatics
- Current Electricity
- Optics (Ray & Wave)
- Mechanics (especially Rotational Motion)
- Thermodynamics
- Magnetism
- Modern Physics
- Oscillations & Waves
- Electromagnetic Induction & Alternating Current
These chapters are frequently tested and form the foundation for more advanced problems. Mastering them will help you confidently handle at least 60–70% of the Physics section.
🧪 Chemistry: Must-Do Topics
Chemistry is often considered the most scoring subject. It is divided into Physical, Organic, and Inorganic Chemistry. The following are the Do or Die chapters for 2025:
- Atomic Structure
- Chemical Bonding
- Thermodynamics
- Electrochemistry
- Chemical Kinetics
- Coordination Compounds
- d-Block and p-Block Elements
- General Organic Chemistry (GOC)
- Hydrocarbons
- Aldehydes, Ketones, and Carboxylic Acids
- Isomerism
These chapters have high weightage and can fetch quick marks if your basics are strong.
📐 Mathematics: Scoring Chapters
With Mathematics carrying 35% weightage in JEE Main 2025, smart selection of topics is essential. Focus on these high-scoring areas:
- Calculus (Limits, Continuity, Differentiability, Definite Integrals, Application of Derivatives)
- Coordinate Geometry (Straight Lines, Circles, Conic Sections, 3D Geometry)
- Algebra (Complex Numbers, Quadratic Equations, Matrices & Determinants, Sequence & Series, Binomial Theorem)
- Probability and Statistics
- Vectors
These topics are not only repetitive in past papers but also offer the best chance for full-score questions if practiced thoroughly.
📚 Preparation Strategies for Maximum Score
Here are a few smart tips to make the most of your JEE Main preparation:
✅ Prioritize High-Weightage Chapters: Start with the Do or Die topics listed above.
✅ Solve PYQs & Mock Tests: Practice from previous years’ question papers and take time-bound mocks.
✅ Clear Doubts Promptly: Use online platforms, tutors, or friends—don’t let doubts accumulate.
✅ Revise Regularly: Make short notes or flashcards and revise them weekly.
✅ Cover the Basics of Other Topics: Don’t leave the rest of the syllabus completely untouched. Aim for 70–80% accuracy in core areas and basic understanding of remaining topics.
✅ Conclusion
Cracking JEE Main 2025 is not about studying everything, but about studying smart. By focusing on these Do or Die chapters across Physics, Chemistry, and Mathematics, you ensure maximum returns for your effort. Combine this targeted preparation with regular practice and revision—and you’ll be well on your way to success.
