Study Strategy for 90+

1

Split the syllabus into 3 parts: Physical (chapters 1–3), Inorganic (4–5), Organic (6–10). Prepare each separately

2

Physical Chemistry is calculation-heavy — practice 5 numericals per chapter minimum

3

Inorganic requires pure memorization — make a one-page summary per chapter of reactions and properties

4

Organic reactions: learn the mechanism, not just the product. CBSE often asks 'why' and 'how'

5

Do 2 full mock papers under timed conditions. AI evaluation catches keyword errors in naming and mechanism writing
