High-yield Focus Areas
- 🔴 Ray Optics + Electrostatics (10 periods each) — both are strong LAQ chapters
- 🔴 Current Electricity + Wave Optics (10 + 8) — SAQs guaranteed from both
- 🟡 AC Circuits (9 periods) — LCR derivation is a recurring LAQ
- 🟡 Dual Nature + Semiconductors (8 + 8) — photoelectric equation and transistor SAQs are repeated
