IT DIDN'T JUST RISE — IT STUCK

On the same short anatomy check, the class's grasp of how the heart is built and how blood moves through it climbed from roughly four in five students to nearly nine in ten.

Demand

THEN THEY ASKED FOR MORE

0%
Asked whether they'd want their other subjects taught the Karkei way, the answer was close to unanimous — only a single student said no. Every one of the four observing teachers said they would recommend Karkei, and rated themselves able to run it independently.

In their words

“NOTHING SHOULD CHANGE. THE SESSION IS FANTASTIC HOW IT IS NOW.”
