I can't recall about here in Australia - I did Chemistry as an elective in the final 2 years of high-school, but I can't recall if everyone did that kind of thing in chemistry in earlier years or not.

...but you also have to remember that high-school was a long time ago for a lot of people, and facts like what the prefix "di" means is hardly something most people are going to need to keep in their heads, so are likely to fade over time.
