Chances are very slim as CIC posted on 23rd August that cap reached. So if courier takes 4 days you missed the chance... but check in 35 days from the time CIC received the documents if your CC is charged or if you paid by BD, then check with the bank if BD encashed...
All the best... and make sure you keep your documents ready in June 2012 beginning itself... and if 1122 is still in the offering next year, send your documents on 26th June 2012 so it reaches on 1st july (or check the exact delivery schedule from courier) in any case don't delay and complete documents should be with CIC on 1st July 2012...
Anyway still I hope you make it this year.
