It is faster now - once you actually get seen you are done on the spot but don't kid yourselves. You still need to get down early to get an early slot. There are 4 desks so if you pick lucky number 13 you have 3 waves to go before you (20-30 min each). And that was arriving at 0815. If you do get there early though (0700 for number one) then you will be out by 0845.
There is just about enough seating as far as I saw but I don't think there were many exam people in.
The bonus is the staff seem to know what they are doing.
