Preparation Tips for CBSE Class 12 Chemistry Syllabus 2026-27
Students preparing for the upcoming CBSE Class 12th Board exams with the science stream must be confused about how to start the preparation for the Class 12 Chemistry exam. No worries! We got you covered with the most effective preparation tips for the CBSE Class 12 Chemistry Exam prep.
Stick to the NCERT First
- Make sure not to get confused with a huge bundle of refrence books, just stick to the NCERT line by line because most CBSE questions come directly from it.
- Solve all in-text and exercise questions without skipping.
Plan Chapter-Wise
- Physical Chemistry (numericals): Practice formulas daily from Solid State, Solutions, Electrochemistry, and Chemical Kinetics.
- Organic Chemistry: Focus on name reactions and mechanisms. Make flowcharts for easy recall.
- Inorganic Chemistry: Learn NCERT tables and exceptions with short tricks.
Practice Previous Year Papers
- Make sure to solve the last 5–7 years’ Question papers and the latest CBSE sample paper.
- Practice in 3-hour slots to improve speed and accuracy.
Make Smart Notes
- Create one-page sheets for reactions with reagents, conditions, and products.
- Use mnemonics for Inorganic to memorize easily.
Revise Regularly
- Spend at least 1 hour daily on Chemistry revision.
- Revise formulas, equations, and tables every weekend.
Don’t Ignore Practicals
- The practical exam is 30 marks. Practice salt analysis, titration, and viva questions from the NCERT Lab Manual.
Focus on High-Weightage Chapters
- Electrochemistry, Solid State, Solutions, Amines, Aldehydes & Ketones, Polymers, Biomolecules, Surface Chemistry, and Coordination Compounds.
Write & Practice
- Don’t just read; practice writing answers and equations, as it has been proven that writing helps to increase long-term memory.
- Make sure to take short breaks, do not sit continuously for 5-6 hours, as it also reduces interest and concentration. By taking short breaks, you can refresh your mind and stay consistent with your routine.
