The CBSE Class 12 Chemistry board exam 2026 requires a strategic study plan that balances conceptual understanding with extensive practice. With the examination approaching as part of the broader CBSE board schedule, students should concentrate on high-weightage topics, accurate numericals and effective answer presentation to perform well
Focus on High-Yield Chapters and Core Concepts
Effective preparation begins with identifying areas of Physics, Inorganic and Organic Chemistry that consistently carry significant marks in board exams:
- Physical Chemistry: Prioritise Solutions, Electrochemistry and Chemical Kinetics through regular practice of numericals involving laws like Raoult’s, Henry’s, and Nernst equations. Careful graph interpretation and labelling also strengthen answers
- Inorganic Chemistry: Develop strong reasoning skills in d- and f-block elements, including trends, oxidation states and oxidising behaviour of compounds like KMnO₄ and K₂Cr₂O₇. Clarify concepts in Coordination Compounds such as hybridisation and ligand bonding.
- Organic Chemistry: Ensure IUPAC nomenclature, step-wise reaction mechanisms, named reactions and conversions are well practiced. Writing mechanisms with correct arrows and intermediates is key to securing full marks.
Students are advised to master NCERT textbooks first, as the majority of questions are derived from this source, and then reinforce understanding through exemplar problems and reference guides.
Practise Numericals and Past Papers Regularly
Numerical problems can markedly influence board scores; thus, daily practice is essential:
- Solve a mix of 1-mark and long-form numericals across topics.
- Use sample papers and previous year question papers to familiarise with board patterns and time constraints.
- Maintain a formula sheet for frequent revision near the exam.
Practising past papers also improves speed and enables students to recognise commonly tested concepts that may appear again in the 2026 paper.
Write Clear and Neat Answers
Answer presentation is as important as accuracy:
- Write neatly with numbered sub-parts and sufficient spacing to aid examiner readability.
- Include labelling of diagrams and graphs wherever applicable, especially in Organic and Physical Chemistry questions.
- For distinguishing tests and mechanisms, use tabular formats and correctly depict electron movements
Teachers also recommend starting the paper with confident questions to build momentum and avoid early panic, saving time for complex or lengthy questions later
Avoid Common Mistakes
Students often lose marks due to execution errors rather than lack of knowledge:
- Misuse of units or incorrect substitution in numerical problems.
- Incomplete reaction mechanisms or missing reagents in Organic Chemistry.
- Unbalanced equations or partial reasoning in Inorganic Chemistry.
Avoiding these recurring mistakes through regular revision and careful answer writing can significantly improve performance.
Plan Smart Revision and Time Management
A balanced preparation schedule should include:
- Daily revision of key concepts and formulas.
- Mock tests to simulate exam conditions and refine time management.
- Mind maps or short notes for quick last-minute review.
Students should also focus on maintaining a healthy routine with adequate breaks to manage stress effectively as exams near.
