I'm asking because very frequently in /r/AskAnAmerican, we get posts asking "how is X taught?" In the US, we have no federal education mandates or controls. Trump dissolved the Department of Education last year, which is reprehensible and should be undone, but it's not actually as damaging as it sounds – 99% of government involvement is on the state level, or in our 13,000(!) independent school districts. The same subject can be taught in wildly different ways depending on the state, school district, specific school, and even down to the teacher.
So how is it in your country? Are curricula set by the national government, or is it decentralized? Are there regional history or literature classes in different parts of the country? How strictly are teachers held to the set curriculum – can they go "off script" or is it very standardized? Do you have parts of the country or your local city with "good schools" vs. "bad schools"? Can you talk with someone from the opposite end of the country from you, and find commonalities in what subjects you studied and when? What about neighboring countries?
