Kids are hardwired to love learning, they will never stop asking questions and exploring the world.
Schools quash that curious spirit. They put kids in a boring, prison-like, highly regimented environment that seeks to teach discipline and obedience to the status quo. Don't think, accept your role in the capitalist machine. If you are bullied, no one will help you, but if you fail to complete work you will be punished. Most of all, get used to not owning most of your time.
Take note of this and try to rekindle your child-like curiousity and love of learning. Ask yourself, do you still have questions about the universe you forgot to ask as a child? Read about the planets, the stars, microbes, machines. But most importantly, do it at your own pace and do it because you still have questions. Not to pass some test, but for you.

They teach people to question things because, basically, the engineers running a system need to know about its flaws to keep the junk pile running. There have been studies about how school culture is used to reinforce norms around how much freedom students ought to have. Teachers from working class backgrounds tend to see school as a means to get a job and tend to teach in districts full of other working class teachers where this is the prevailing sentiment
