Same, I was never taught graphing in school despite being in the top class for maths. I just assume that US school math and science in general is more fleshed out than my basic curriculum, as there’s always media depicting high schools teaching things I was never; equation/algebra graphing, and enzymes like prophase, anaphase and stuff mitochondria. There was a meme about “Mitochondria is the powerhouse of the cell”. Never heard that in school aha
