Chocatime Project: Life Without Unnecessary Knowledge

"Why should I learn this? It won't be useful in life anyway!" - often ponder the schoolchildren of Mid-City. And indeed, not every adult remembers tangents, gerunds, and Ohm's laws. So why learn it?!
The dream of schoolchildren comes true: a project "Chocatime" opens in the city - a place where kids learn real skills instead of school that will be useful in life. The children are thrilled, and the parents are delighted. No more school, homework, journals, and other unnecessary things. But before becoming a participant in the project, each child must erase their school knowledge from memory. Is it really that easy to live only with "necessary" knowledge? And who came up with this wonderful project? A graduate of an ordinary school, Mark, decides to find answers to these questions and understand if modern people need education.
