Hi Graham,

That's a great question. The Khan Academy curriculum can be translated into 37 different languages. With each language, the content will change to what is relevant for the region that you selected. Please note, however, that the courses available in languages other than English will be constricted and you might not be able to find every class that you are looking for.

But if you are wanting to keep the language settings in English, the content will be centered around the standard US curriculum.

I hope that helps! Let me know if you have any additional questions.
