Full Syllabus Coverage Report (Forensic Audit)
- Total Topics Covered: Lagbhag 95% syllabus papers me cover ho chuka hai. Papers pattern ab 'Ratta' se hatkar 'Derivation + Numerical' combo par shift ho gaya hai.
- Total Topics Never Asked (in 2024-25):
- Potentiometer & Meter Bridge: 2023 ke baad se ye topics papers se gayab hain (New NCERT effect).
- Transistor as Amplifier/Oscillator: Bilkul nahi pucha gaya recent sets me.
- Van de Graaff Generator: Syllabus se hatne ke baad paper me nahi dikha.
- Most Rotated Micro-Concepts (Ye topics har saal ghuma-fira ke aate hain):
- Unit 1: Gauss Law ka derivation (Shell ya Wire) hamesha aata hai.
- Unit 6: Huygens Principle vs YDS Numerical – inme se ek jarur milega.
- Unit 4: Transformer ki theory ya phir LCR ka numerical – ye rotation fix hai.
- Unit 9: PN Junction Rectifier (Full Wave) ab Transistor ki jagah le chuka hai long answers me.
- OR Pattern Observations (Internal Choice ka Pattern):
- 5 Marks wale section me Optics ka question aksar EM Waves ya Dual Nature ke sath option me nahi, balki Optics ke hi dusre part (Ray vs Wave) ke sath aata hai.
- Electrostatics ke heavy derivation (Capacitor/Gauss) ke option me aksar Magnetism (Moving Coil Galvanometer) ya AC (Transformer) diya jata hai.
- Agar question paper tough set (jaise 2024 Set FT) ho, toh Numerical ka ratio 40% tak chala jata hai.
- Internal Choice Behavior:
- UP Board ab seedhe "Derive this" puchne ke bajaye, "Derive formula and solve this numerical" pattern follow kar raha hai.
- Internal choice me ek question 'Pure Theory' hota hai aur dusra 'Mathematical/Numerical' hota hai. Students ko choose karte waqt dhyan dena chahiye.
