My 12yrs old son loved his 5 days residential camp. It's a pretty unique combination of spending time away while working on a STEM project, I haven't found any other company doing this so hard to compare. It's quite expensive, though between the full board in individual room and the many tutors around it definitely doesn't feel like a rip off. The description of the courses is obviously a bit overselling the actual activity. For example my son did "Python AI" which sounds super fancy, but I'm reality all they did was some basic Python coding that used AI libraries. Didn't really go into teaching/understanding those.... Still, I don't think it would have been possible to go beyond that in 5 short days with kids as young as 12, so not holding it against them.
