NEET Physics is 45 questions, 180 marks drawn from ~29 chapters across Class 11 and 12 — roughly a 45:55 split, with Class 12 slightly ahead. This page lists the formulas that actually get asked, chapter-wise, each tagged HIGH / MED / LOW yield from previous-year trends. Consistently highest: Current Electricity, Ray Optics, Modern Physics, Electrostatics and the Mechanics block (Laws of Motion, Work-Energy, Rotation).

NEET 2026 pattern — and how to use the yield tags
NEET Physics gives you 45 questions worth 180 marks, roughly a quarter of the 720-mark paper. Marking is +4 for correct, −1 for wrong, and the 2026 pattern dropped the optional Section B — all questions are compulsory. Across the full paper that's 180 questions in 180 minutes: one minute per question, which is why formula recall must be automatic, not reconstructed.
Every chapter below carries a yield tag based on previous-year question trends: HIGH chapters reliably deliver 2–4 questions each year, MED around 1–2, and LOW often 0–1. Tags guide revision order, not what to skip — with negative marking, a single question from a "low" chapter still swings 5 marks between a right answer and a wrong one.

FAQs
How many questions come from Physics in NEET 2026?
45 questions worth 180 marks — a quarter of the 720-mark paper — with +4 for each correct answer and −1 for each wrong one. The 2026 pattern removed the optional Section B, so all questions are compulsory.
Which chapters have the highest weightage in NEET Physics?
Current Electricity, Ray Optics, Modern Physics, Electrostatics, and the Mechanics block (Laws of Motion, Work-Energy-Power, Rotational Motion) consistently deliver the most questions year after year.
Is NEET Physics from Class 11 or Class 12?
Both — roughly a 45:55 split across about 29 chapters, with Class 12 slightly ahead. Estimates vary by source and year, so neither class can be skipped.
How many formulas do I need for NEET Physics?
Around 200 across both classes, but the yield is uneven: the high-yield chapters' formulas answer the majority of questions, which is why revision order matters more than raw count.
Are Class 12 board formulas enough for NEET Physics?
No — NEET draws about 45% of its Physics questions from Class 11 chapters like Mechanics, Thermodynamics and Waves that the Class 12 board paper never touches.
Should I skip low-weightage chapters in NEET Physics?
No. A low-yield chapter still averages roughly one question, and with +4/−1 marking that's a 5-mark swing. Revise them lightly and last, but don't drop them.
Is there a NEET Physics formula sheet in Hindi?
Yes — the handwritten NEET formula sheet linked above is available in both English and Hindi medium versions.
How do I revise 200 physics formulas before NEET?
Revise in yield order — high-yield chapters first and repeatedly — write formulas from memory weekly rather than reading them, and learn the derived shortcuts like KE = p²/2m that skip whole algebra chains under time pressure.
