I have to say I take a rather dim view of CTC on this...
I emailed them stating that I applied but was rejected at phase 1 (no idea why btw - they must have not liked what I wrote...) still waiting for a response after 2 days...
Anyway I suspect the answer will be a no.
On a slightly different point though why not just let people who failed at stage 3/4 retry? Who is going to apply now that didn't apply in the original window...which they had already extended once back in May!
