So based on my own experience, heres my timeline:
04.08-Assesment day
08.08-Reference checks
19.08-Medical and security email
29.08-Offered Ground School for 12.09
Pretty quick for me, but based on what ive read, some people wait months or sometimes more than a year. I think they have a few ground schools left-1 in september and i think 2 in october. Based on the amount of assesment days theyve already had, Id take a guess and say if successful youd be looking at early next year.

I wouldnt spend too much time on my application! I spent a whole of like 15mins. Its more about how you present yourself at the actual assesment day and how you communicate with others.
