I don't think anyone is sure if it's assesed or not. But I belive there are people who have failed on it, and also people who have gone to stage 2 without having to do it.
I'd say your best bet is to assume it's being examined, how ever I belive it's a bad idea to try and find the right "profile". It's like all the rest of the assesment, either you have it or you don't, so just be honest and do your best and hopefully it will be enough!
*fingers crossed*
