The idea of learning is one that keeps us engaged and interested in the world around us. If we can learn something new, perhaps we can also expand our mind and learn something useful from it.
I think the main problem is that the school system is so inefficient that it would take several hours of work to complete a lesson at the elementary school level. I actually see a good reason why a school will not be able to fully complete a lesson at the elementary school level. That’s why I’m giving a game with the most advanced level from my school.
