Priodemy launches free interactive Science and Maths for CBSE Classes 9 to 12

Priodemy today made Priodemy for School available to all students at no cost. The release covers the CBSE Science and Mathematics syllabus for Classes 9 through 12 across 125 chapters, each combining written explanation, worked NCERT and previous-year solutions, and a short practice quiz.

The material requires no account, no application and no payment. Every page is a normal web page that loads directly, which means it also works on low-end phones and over slow connections — the conditions most Indian students actually study in.

Simulations rather than static diagrams

The part of the release Priodemy considers most significant is a set of 25 interactive simulations built for the topics students most often get wrong on paper. Each one is computed from the same formula the examination expects, rather than being an animation drawn to look approximately right.

Dragging the object in the mirror and lens simulations redraws the ray diagram from the mirror and lens equations under the standard sign convention, so a student can watch the image flip from real to virtual at the focus instead of memorising the six standard cases. The series LCR simulator sweeps frequency and shows current peaking exactly where inductive and capacitive reactance cancel. The definite-integral visualiser narrows its rectangles until the sum converges on the area, which is the definition of the integral rather than an illustration of it.

Others cover projectile motion, simple harmonic motion, the photoelectric effect, electromagnetic induction, charged particles in magnetic fields, VSEPR molecular shapes, titration curves, reaction kinetics, the periodic trends, probability trees and Bayes’ theorem, and three-dimensional vectors. Each simulation opens full-screen and carries a written explanation of the underlying physics or mathematics, what to try, and the mistakes that commonly cost marks.

What is covered

• Class 9 — Science and Mathematics
• Class 10 — Science and Mathematics
• Class 11 — Physics, Chemistry and Mathematics
• Class 12 — Physics, Chemistry and Mathematics
• 25 interactive simulations spanning Physics, Chemistry and Mathematics

Availability

Priodemy for School is live now at priodemy.com/school. There is no paid tier, no trial period and no advertisement-free upsell; the material is the same for every visitor.

Schools running Priodemy EduSuite, the company’s school management platform, get the same workspace bundled for their students at no additional cost.

“Most students meet these topics as a formula to memorise and a diagram to copy. The formula is not the hard part — picturing what it describes is. A simulation that is actually computed from the equation lets a student build that picture themselves, and it costs nothing to give away.”
