@ Rutele: I think Matichk's right. You have to be under 25 in order to apply and they wouldn't accept your application in the first place, if your age would be an issue.
I will turn 24 too in September and my age is the last thing that bothers me right now regarding my application. It's strange though that you weren't prioritised to attend phase 1 in June.. Maybe you will be invited for Phase 1 in July?
