I sat my test at 1pm in Sheffield and I am yet to hear back. They said it could take up to 14 days or even up to 30 since they are on the road recruiting at the moment. However they did mention that they will try and mark papers in their spare time and let candidates know as soon as they have results.
Rather than them choosing the best/worst I think it could just be chance that they happen to have marked the papers of the two previous posters and one was a pass and one was a fail, rather than anything else.
I am pretty sure I passed the diagramming paper and failed the cubes, but time will tell.
