I'm not sure you can generalise: for example Math can be done 100% in French (and is usually taught like that in France, at least up to the undergraduate level)

I'm not sure you can generalise: for example Math can be done 100% in French (and is usually taught like that in France, at least up to the undergraduate level). I've no doubt in other languages too. Computer science is a little harder, but also doable. But I would say most people deeply engaged in the field of computer science also know the English terms regardless of their mother tongue.
