Hi Roy! 

Regarding the restriction of subjects, this is because Khan Academy does not share the same content across languages. Our most complete version is the English one, which you were able to access when going for https://khanacademy.org/. But, when you hit https://nb.khanacademy.org/, you go for the Norwegian version of the site, which has much less content available. 

That said, about your first issue, could you please submit a support ticket for this issue? This way our support channel can have a deeper look at it.

Please be sure to include a link to your profile and also take a look at this article to make sure you send an effective bug report.

Thanks in advance and all the best!

Hi Alexandre,

Thank you for the answer.

I actually figured out that language barrier on content, it also fixed my classroom issue.

I just changed the language settings to English for both and everything righted itself, my son has no problem with English so there really is no great problem with that either.

Thanks again!
