No, of course it doesn't form an integral part of a proficiency exam, what a ludicrous thing to suggest! That said you haven't got the foggiest about what is involved in teaching actual language exams and certainly couldn't pass a C2 yourself, so it's not a total shock that you don't know what's involved in attaining a C2 certification!

My it's are just fine, thanks. If there had been an extraneous use of an apostrophe, it will be due to autotext on my smartphone. And a stray apostrophe is not the same as saying things like 'have credibility for <someone>' or insisting that 'sexist' means somebody is sexually attractive!

You may never outright claim to be an authority, but you post as if you are when you rubbish techniques and confuse methodologies (for example thinking TPR is drilling, or that making faces forms part of a lesson plan). By saying thwas things it appears that you are rubbishing these methods because you know better. But as we all saw, when given an opportunity to say how it should be done instead you couldn't. So as you have nothing constructive to add (seeing how you admit you have no experience of or interest in) to discussions about those area's of teaching, you should just stay out of it and stop making yourself look foolish. Not that you will, because you believe you know best... Contrary to your own admission of having no experience nor being qualified in that field!

I don't like unscrupulous language kills any more than you, and I do not defend them. This is a fallacy you have dreamt up! I posted a long warning post about working at EF, something you chose to forget because it doesn't fit with the delusion you have created in your mind.
