School.. please.

In my opinion, school was made to brainwash us. Like, what do you mean, there are things that teachers don't teach about the country we live in? I know that they can't teach us all the history but... i don't know, that's the bare minimum. Because why do I have to look like an idiot when I learn that France is not as good as it is?? Why??? Or when I learn that colons and "masters" use to make shoes and clothes out of slave's skin?? Why the hell do they don't teach us important things like that? And that's were I'm coming at. School was made to brainwash us, to create robots when you get your diploma. We weren't meant to know about what actually happened in the past, that's why each country focuses on teaching about the great and sweet side but not the dark and gloomy side. And why do they make many exams like that? I'm taking France in example. We have a huge exam at the end of 9th grade, junior year and senior year but the problem is, the exam of the 9th grade doesn't have any recognition on the territory. As well as the exam of junior year. Why create so many exams if they don't mean anything? Even the exam of junior year starts to lose its value. When you want to search for a work and you pull out your junior year's diploma, it's not sure that they will hire you because it has no longer value like the old time. The creation of this much exams is USELESS.

(Please this is just a theory, don't take me too seriously, I'm just tired of studying.)
