JEE Main
The JEE map on the same engine, with interactive lessons and simulations for Physics, Chemistry and Maths.
The research
Three published models. One plan
Item Response Theory from psychometrics, FSRS from memory research, and knowledge tracing concept by concept. Each is written out in our whitepapers, so you can check the maths.

Not chapters. Concepts.
A chapter score says Oscillations is 60%. Lumi tracks the 150 concepts inside it, and what each one needs first.
The mapAbility, not percent
Same score. Different students.
Two papers with 6 of 10 right are not the same. Lumi's 2PL model weighs which questions you got right.
