Score Higher by Focusing on What Matters Most
The Class 12 Board Exams are a major milestone for every student—and with tight schedules, entrance exams like NEET/JEE, and pressure to score high, it’s crucial to study smart.
Instead of trying to study every chapter equally, smart students focus more on the high-weightage and frequently asked chapters. In this blog, we’ve compiled the most important chapters for Class 12 CBSE Science students (Physics, Chemistry, Biology, and Mathematics) based on past papers, CBSE trends, and expert analysis.
📘 PHYSICS – Important Chapters (2025)
Physics can be conceptually challenging, but high-scoring with the right prep.
🔹 1. Electrostatics
- Important for both theory and numericals
- Concept-heavy but high scoring
- Focus on derivations, diagrams, and application-based questions
🔹 2. Current Electricity
- Frequently asked in boards and JEE
- Numerical practice is essential
- Focus on Ohm’s law, Kirchoff’s rules, Wheatstone Bridge, potentiometer
🔹 3. Magnetic Effects of Current & Magnetism
- Expect long-answer derivations
- Fleming’s rule, torque on a coil, moving coil galvanometer are crucial
🔹 4. Electromagnetic Induction & AC
- Conceptual + numerical
- Focus on Lenz’s Law, RMS value, peak value, power in AC circuits
🔹 5. Ray & Wave Optics
- Major weightage
- Ray diagrams, lens/mirror formulae, Young’s double slit experiment
🔹 6. Dual Nature of Matter & Atoms
- Usually short answer but conceptual
- Photoelectric effect is very commonly asked
🧪 CHEMISTRY – Important Chapters (2025)
Chemistry = 1/3 Organic, 1/3 Inorganic, 1/3 Physical. Focus accordingly.
🔹 1. Solutions
- Numerical-based + conceptual
- Focus on Raoult’s Law, colligative properties, concentration terms
🔹 2. Electrochemistry
- Diagrams + numericals
- Nernst Equation, cell potential, Galvanic & Electrolytic cells
🔹 3. Chemical Kinetics
- Important for both Boards & NEET
- Focus on order, rate, integrated rate law, units
🔹 4. Coordination Compounds
- Tricky but high scoring
- Focus on IUPAC naming, hybridization, crystal field theory
🔹 5. Haloalkanes and Haloarenes
- Organic chemistry basics start here
- Mechanisms, SN1/SN2 reactions, naming important
🔹 6. Alcohols, Phenols and Ethers
- Reaction mechanisms and conversions are common
- Good for 3–5 marks questions
🔹 7. Biomolecules & Polymers (for short questions)
- Easy to score in 1–2 mark sections
- Do not skip—comes every year
🧬 BIOLOGY – Important Chapters (2025)
(For PCB students – High NEET overlap)
Biology is more theory-based but requires clarity and presentation.
🔹 1. Human Reproduction + Reproductive Health
- High probability of 5-mark questions
- Diagrams are very important
🔹 2. Genetics & Evolution
- One of the most repeated chapters
- Focus on Mendel’s laws, genetic crosses, evolution theories
🔹 3. Molecular Basis of Inheritance
- Complex but crucial
- Central dogma, structure of DNA/RNA, genetic code
🔹 4. Biotechnology (Principles & Applications)
- Usually asked in both Boards and NEET
- Recombinant DNA tech, vectors, processes
🔹 5. Human Health & Disease
- Easy + important
- Viruses, immunity, AIDS, vaccination concepts are often asked
🔹 6. Ecology & Environment (all chapters)
- Very scoring, typically asked for 4–5 marks
- Revise thoroughly for easy marks
➗ MATHEMATICS – Important Chapters (2025)
Maths is all about practice. Here’s what to focus on for max returns:
🔹 1. Relations & Functions
- Basics of sets, functions, types of relations
- Comes every year—don’t skip
🔹 2. Inverse Trigonometric Functions
- Short but scoring
- Direct questions are common
🔹 3. Matrices and Determinants
- 10–12 mark weightage
- Focus on properties, inverse, solutions of equations
🔹 4. Continuity and Differentiability
- Key chapter for Calculus
- Limits, derivatives, continuity questions are common
🔹 5. Application of Derivatives
- Maxima/minima problems, tangents, and increasing/decreasing functions
🔹 6. Integrals & Area Under Curve
- Heavyweight topics—expect at least 10–14 marks
- Practice different types of integration
🔹 7. Probability
- Usually conceptual + formula-based
- Bayes theorem, independent events
✅ Tips to Make the Most of These Chapters
- Solve previous year questions to spot recurring patterns
- Use NCERT as the base for concepts and definitions
- Practice diagrams and derivations neatly (especially in Physics & Biology)
- Create summary notes for each chapter
- Give mock tests chapter-wise and full-syllabus for time management
