Well, it's about 10 years since I did my entry test so it might have changed in the meantime!
But I got a couple of case studies and was asked to comment on various aspects of the situation presented. They were both in areas that I had no experience of but it was looking for the things that you would look for in the situations - such as looking at needs very broadly and not in terms of service provision, in an anti-oppressive framework and some common sense.They weren't looking for 'right' answers (as I had no idea at that point what a right answer would be) but just thoughtful and attentive.
Of course, they might have completely changed the structure of them now!
