Syllabus-Mapped Physics Resources

Every chapter of the CBSE, ICSE/ISC, IB and IGCSE physics syllabi — mapped to our interactive simulations, official textbooks, past papers and short explainer videos. Built for board exams, JEE and NEET.

NCERT heads-up: the 2023-24 onward editions are rationalised — chapters and topics were deleted. Old playlists and notes often cover removed material. Check the official list ↗ before you revise from anything dated before 2023.

Ray Optics in 90 secondsThree rules run the whole chapter — reflection, Snell's law, and the lens equation — plus total internal reflection, the sign convention, and how the eye is corrected.90s explainer

Electrostatics in 90 secondsOne idea — charge — in three languages: Coulomb's force law, the electric field, and potential; ending on Gauss's theorem and the parallel-plate capacitor.90s explainer
