Idk what middle school really is because it’s not been a thing at any of the schools I’ve been to, but it’s definitely something you do a lot earlier than calculus. If calculus comes in in your last three or four years of high school, quadratics are what you’re doing for at least two years before that.
It’s the step between primary and secondary school that a lot of countries have, also known as intermediate school, junior high school, junior secondary school, or lower secondary school: https://en.wikipedia.org/wiki/Middle_school
