Different cities, different grade groups, three months apart — and the results move the same way. Engagement up. Understanding up. Demand up. Teachers convinced.
Measured two different ways — self-rating at Rajavva, a knowledge check at Green Valley — students left both rooms knowing more about the heart than when they walked in.
The honest gaps from Rajavva became the roadmap. Every one showed up fixed at Green Valley — and the experience score rose from 4.3 to 4.75.
“ACROSS TWO SCHOOLS, THE SAME EFFECT — NOT NOVELTY, BUT A REPEATABLE WAY TO MAKE HARD CHAPTERS LAND.”
Combined view of two early, in-class pilots run on Karkei's own kit with the class teacher present. Figures verified; self-reported on small samples and presented as directional evidence, not a controlled trial. Rajavva 62%/82% shown as 3.1/4.1 of 5 normalised to a percentage.
