Low Weightage (2–5%) | Attempt only after high/medium chapters are strong. - Focus on concept clarity (not depth). - Revise formulas and basic NCERT examples. - Practice 10–15 questions just for familiarity. |
Very Low Weightage (<2%) | Can be skipped if short on time. - If time permits, cover basics only. - Revise formula sheets, but don’t over-invest. |
