The NCERT Chemistry textbook is the most important resource for CBSE board exams. Read every chapter carefully, highlight important concepts, and make short notes for quick revision.

Practice Questions Daily

Regular practice is important to mastering Chemistry. Solve:

  • NCERT exercises after every chapter.
  • Previous years' question papers to understand exam patterns.
  • Numerical problems in Physical Chemistry.
  • Reactions and equations in Organic and Inorganic Chemistry.

Make Conceptual Notes and Mind Maps

Creating short notes, reaction charts, and formula sheets helps in quick revision before exams. Mind maps are especially useful for understanding reaction mechanisms in Organic Chemistry.

Revise Regularly

  • Dedicate one day a week to revision.
  • Revise Organic Chemistry mechanisms and name reactions frequently.
  • Solve at least one sample paper every week after completing the syllabus.

Focus on Important Topics

Some chapters carry more weight in exams. Pay extra attention to:

  • Electrochemistry & Chemical Kinetics – Important numerical problems.

Solve Sample Papers and Mock Tests

Attempting CBSE sample papers and mock tests improves time management and boosts confidence. Try to solve at least 10 sample papers before the final exam.

Stay Consistent and Avoid Last-minute Cramming

Chemistry is best understood through regular study rather than last-minute memorisation. Stick to your schedule, revise regularly, and practice consistently to excel in the exam.

By following this CBSE Class 12 Chemistry study plan, you can strengthen your conceptual understanding, improve your problem-solving skills, and score high marks in both board exams and entrance tests. Stay focused, practice consistently, and success will follow! 

Tips on How to Use the Class 12 Chemistry Syllabus

The Class 12 Chemistry syllabus is vast, but with the right approach, you can study efficiently and score well in your board exams and competitive tests like NEET, JEE, and CUET. Here are some useful tips to help you make the most of your syllabus:

Understand the Weightage of Each Topic

Some chapters carry more marks in exams than others. Prioritise high-weightage topics like:

  • Physical Chemistry: Electrochemistry, Chemical Kinetics, Solutions
  • Inorganic Chemistry: Coordination Compounds, d- & f-Block Elements
  • Organic Chemistry: Aldehydes, Ketones, Carboxylic Acids, Biomolecules

By focusing on these topics first, you can secure a good score.

Break the Syllabus into Small Sections

Instead of trying to study everything at once, divide the syllabus into smaller, manageable parts:

  • Week 1-2: Solid State, Solutions
  • Week 3-4: Electrochemistry, Chemical Kinetics
  • Week 5-6: Surface Chemistry, Metallurgy, p-Block Elements
  • Week 7-8: Organic Chemistry (Haloalkanes, Alcohols, Aldehydes, etc.)

This method helps avoid last-minute stress and makes revision easier.

Use NCERT as Your Primary Resource

NCERT textbooks are the most important books for Class 12 Chemistry. Most board and competitive exam questions are based on them.

  • Read line by line to understand concepts clearly.
  • Highlight important points for quick revision.
  • Practice NCERT questions at the end of each chapter.

Make Summary Notes for Quick Revision

Writing short notes in your own words helps you remember topics better. Your notes should include:

  • Important formulas from Physical Chemistry
  • Reactions and mechanisms in Organic Chemistry
  • Properties and trends of elements in Inorganic Chemistry

Use flashcards or charts to memorise key concepts.

Practice Numerical Problems Regularly

Many questions in exams involve numerical calculations, especially in Physical Chemistry.

  • Solve different types of numerical problems from topics like Electrochemistry, Chemical Kinetics, and Solutions.
  • Understand the formulae and their applications instead of just memorising them.

Solve Previous Year’s Papers and Sample Papers

Practising previous exam papers gives you an idea of question patterns and difficulty levels.

  • Try to solve them within the time limit to improve speed and accuracy.
  • Focus on frequently asked questions to predict important topics.

Learn Organic Chemistry Reactions with Tricks

Memorising organic chemistry reactions can be difficult, but using mnemonics and flowcharts makes it easier.
For example:

  • Cannizzaro Reaction: "2 Aldehydes with No α-Hydrogen → Alcohol + Carboxylic Acid"
  • Friedel-Crafts Reaction: "Benzene + Alkyl Halide → Alkylbenzene (Using AlCl₃ Catalyst)"

Writing reactions repeatedly also helps in memorisation.

Focus on Conceptual Understanding in Inorganic Chemistry

Instead of rote learning, understand the trends and logic behind the periodic table.

  • Learn group properties rather than memorising them separately.
  • Compare elements within a group to understand periodic trends (like electronegativity, ionisation energy).

Revise Regularly to Retain Information

The key to mastering Chemistry is consistent revision.

  • Revise every week to keep topics fresh in your memory.
  • Use a revision timetable before exams to cover all topics effectively.

Using the Class 12 Chemistry syllabus 2026 effectively requires planning, consistency, and regular practice. Follow these tips, focus on concept clarity, and practise enough questions to score well in your exams.
