CrazyFokker...don't worry about failing Stage 2 mate. I did the same and I'm now off to NZ on CP57 in January.
As for the Class 1 Medical.....I didn't get my Certificate until approx 2 weeks later (via the mail) as they wanted to check something on my ECG. Turned out ok though. Daphne at CTC reassured me by saying this is fairly common. So, any time up 2 weeks I suppose but if all's fine on the day then you'll get your certificate that day.
