CBSE Class XII Physics
Built from 43 board papers (2024–2026): 1,690 questions classified into 74 concepts and ranked into three tiers by how often — and for how many marks — the board asks them.
The tier map
Not all chapters deserve equal hours. The tiers tell you where the marks concentrate.
Appears in almost every paper
Concepts like ray optics, electrostatic potential and EMI that the board asks relentlessly — high frequency, high marks. Master these before anything else.
Appears in most papers
Reliable scorers that round out your paper — frequent enough to matter, predictable in form.
Appears occasionally
Low-frequency concepts you cover last — or strategically skip when time is short.
