usually:
1 fail in the theory it's allowed
1 retake on the cpl/ir/me is also allowed
nayra, sit tight, usually if you have passed the first filter ryanair won't say no, you will get the call from cae, and if they like what you say in the call, the will tell you that you will be invited for an interview right away (you might have to wait for an email with the date though)
good luck
And just to humour those people who don't understand what this thread is for: Join REPA and don't join ryanair, you will only fly 600 hours a year.
