Had my assessment yesterday. It's all pretty intense, straight from one thing into another with very little space to breathe, and by the end of the day I was really knackered. It involved very little interaction with the people administering the tests and because it's not clear what standards they're looking for, it's almost impossible to say how I did - just got to wait and see really. As long as you do all the practice stuff and work on the bits you're not so good at, you should be alright though.
To everyone else in the process, anxiously awaiting a result - good luck.
