what if kids designed their own classes response

In class, we watched a video about what if kids designed their own classes. They could do whatever they desired, as long as they were learning something. One kid was writing a book, and another boy was learning about snowboarding. They would still go to their regular classes, but for one semester, they would have no test or quizzes. They would teach themselves new skills. This idea reminds me of genius hour. You have your own responsibilities and you make your own criteria, but you still have teachers checking up on you to see your progress. At Fraser Heights we should have this system for grades 11 and 12. By these grades we have an idea of what we want to do in life and we have basic logic such as math, science etc. But, there are disadvantages with this idea such as missing out on learning and basic planning. Most kids in grades 11 and 12 have spare blocks so why not for one semester they create their own classes? This is something to consider!
