@HighOnYaoi i think it doesn't make sense in their situation. But from my experience as a peruvian, they teach u algebra when u're 11, chemestry at 14 and physics at 15, in public schools. If u are in a good private, it changes. Sorry, idk how to write well
@YEPpalomas Well, in my country we officially start learning chemistry, physics and biology in 9th grade but our mathematics levels are pretty hard even for lower grades. And our private and public schools pretty much teaches the same thing with a little difference of environment.
