This is probably going a bit off topic, but this begs the question, what SHOULD school be teaching you?
Personally I think everybody should learn about their own history, culture and religion, which is the basis of every civilization, then branch out into other regions of the world. In this day and age of immigration and internationalization, it would help to solve problems and misunderstandings that people have with each other.
They should also be teaching you HOW to think, to think critically, to not just accept what you're told and what other people say, learning how to express and articulate your opinions clearly, based on facts.
I watched a lecture give by a senior Japanese teacher of martial arts who explained that, when he left school back in the 1940s, all Japanese children had a basic knowledge of Japanese history and important historical figures and events. These days, according to him, Japanese children leave school not knowing much if anything about this sort of thing. In my opinion, this will hamper the development of your society and your culture, and leave people more adrift and rootless.
I've seen American academics say a similar thing, that students enter university these days knowing far less than they used to.
There's an ugly, sneering, bigoted attitude these days towards having an understanding of and pride in your own history and culture (which often gets described as being bigoted and racist itself), and using that as a basis with which to take your own culture and civilization forward. There is a big movement to destroy that, which has led to the election of a similar bigot like Donald Trump to rail against it. This is a worrying development which I think could be solved by the kind of education I described above.
