Tomato_soup,
I had my assessment day in June and one of my referees was contacted about a month after that. It was then about another 2 months until I was asked to complete the medical.
Now I am just waiting for an offer, apparently I will be notified of this in the next couple of weeks.
I know what the suspense is like! I still won't believe i'm in until I am actually there on the first day of the course.
Hopefully you hear something soon! Good luck.
