I think the question can it really get your true ability um I'd say yes and no. How can we assess someone's language level without the person realizing that they're being assessed is sort of a bit difficult isn't it? You need an exam to be fairly short or as short as possible really to make it practical. The best way to handle this is just to make sure that you're on point and that you inform before you go into the examiner that you're actually like at your peak ability, he says.
