I've seen this on several posts now where someone outside the USA will see someone talking about their school experience here, and they'll ask "wait, do schools in America do X?"
I started noticing it on my own post that blew up about my old teacher's extra credit policy. Too many people asked this for me to want to answer individually, but, like, I want to be clear, for almost everything you want to ask from one American's account of their education, the answer is Yes and No. Do American teachers actually teach literature primarily with multiple choice tests? Well, several of mine did! Don't they use more essay and short answer questions? Well, other people's did!
We have 50 states that all have their own standards on education (though Texas and California have outsized influence on certain nationwide standards). There is the divide between public schools (more standardized to state standards) and private schools (they do their own thing to some extent, the extent they're allowed to can depend on the state). There is a spectrum of private schools that are the fancy ones that are meant to provide better education, and ones that are made with a focus on religious indoctrination (Catholic schools often have some elements of Both). There is a temporal divide, there have been huge changes in the legislated standards of education from when the millennials and older on Tumblr would have been in school, to what the teens and early twenty-somethings experience/d, to what the current teachers on here are expected to do. (No Child Left Behind is the most major and notable but not the only legal change).
My experience at a Midwestern religious school that was constantly scraping for money in the '00s will be very different from a public school in a major city in California today, which will also be different from a private school in Utah today, etc etc. When someone talks about their personal school experience that might just mean that's what their school did, not that it's something that the whole country does.
