Took the examination today. I can tell you for sure that it's not more difficult, than sample papers, but it's true that there are some terms and notions which are not mentioned in the textbook. I guess it might be easier for those who have taken a preparation course. But still - it's very easy. ) I can think of three reasons for taking the exam: you employer requires it, you need the experience of taking an international exam (my case), or you have no idea what 'a noun', 'a verb' or 'an interaction pattern' is. )
Unfortunately I'm not really aware of the assessment criteria, that's why I can't even imagine what grade I could get. I'm also a little bit afraid because of the fact that I was rather sleepy during the first and the second parts of the exam. ) Nevertheless, what's done can't be undone. )
