Attempt the paper under exam-like conditions to improve speed and time management.
4. Practise Numerical Questions
For Physical Chemistry, write the solution systematically:
Given → Formula → Substitution → Calculation → Final Answer
Always check units and significant values where applicable.
5. Revise Chemical Reactions
For Organic Chemistry, revise important:
Reagents
Conditions
Conversions
Named reactions
Products
Mechanism-based concepts
6. Revise Inorganic Chemistry
Use NCERT to revise:
Properties
Reactions
Trends
Coordination compounds
Important compounds
Exceptions
7. Analyse Your Mistakes
Classify mistakes into:
Conceptual mistake
Formula mistake
Calculation mistake
Reaction mistake
Reagent mistake
NCERT fact mistake
Question interpretation mistake
Time-management issue
Why Solve the Class 12 Chemistry 2026 Paper?
Solving the previous-year paper can help students:
Understand the board-exam question format
Practise Physical Chemistry numericals
Revise Organic Chemistry reactions
Revise Inorganic Chemistry concepts
Improve calculation speed
Improve time management
Identify weak chapters
Practise application-based questions

The current CBSE Chemistry course structure assigns 70 marks to theory over 3 hours, with the 10 prescribed units carrying different marks.
Class 12 Chemistry Previous Year Papers
Students can practise multiple previous-year papers for broader preparation.
Recommended practice order:
2026 → 2025 → 2024 → 2023 → Sample Paper → Mock Test
Previous-year papers should be used along with NCERT, sample papers, chapter-wise questions and regular revision.
CBSE has also published the Class XII 2026–27 Sample Question Paper and Marking Scheme, including Chemistry.
NCERT Class 12 Chemistry Preparation Strategy
Follow this simple cycle:
NCERT Reading → Formula Revision → Reaction Revision → Chapter Practice → Previous-Year Paper → Mistake Analysis → Revision
For Physical Chemistry, focus on formulas and numerical practice.
For Organic Chemistry, focus on reactions, reagents, conversions and reaction-based questions.
For Inorganic Chemistry, give special attention to NCERT facts, properties, reactions and coordination compounds.
