Private school uses AI to teach students in just two hours a day

Has someone run a test on students? I've seen a lot of claims, but most dessapear when the students take an exam in a controlled environment.

> The rest of the day is devoted to “life skill workshops,” which can mean climbing 40-foot rock walls, assembling a piece of IKEA furniture or solving a Rubik’s Cube.

Has someone run a test on the ability of the students to solve the Rubik's cube? Is it a "life skill"?
