How to Score 90+ in CBSE Class 12 Chemistry, a Board-Paper Strategy
How to score 90+ in CBSE Class 12 Chemistry, covering high-weightage chapters from real board papers, named reactions, reasoning questions and numericals.
Class 12 Chemistry has three strands: Physical (numericals), Inorganic (facts and reasoning) and Organic (reactions and mechanisms). Each needs its own practice.
Where the marks are

Averaged across 8 CBSE Class 12 Chemistry board papers, 2023–2026. All chapters
Strategy by strand
- Physical (Solutions, Electrochemistry, Kinetics): formula-based numericals. Write units and show each step.
- Inorganic (Coordination Compounds, d- & f-Block): nomenclature, isomerism and VBT/CFT for coordination compounds, and trends with reasons for the d-block.
- Organic: named reactions, conversions and "give reasons" questions. Keep a reaction sheet. Named reactions list
NCERT is key
Many questions come straight from NCERT in-text questions, exercises and the text itself. Read the text, not just the summary.
Final weeks
Daily reaction and conversion practice, two full papers a week, and a numerical set every other day.
