As far as I'm concerned people have no reason to complain about the CAA withdrawing the exams at the end of June. They put this rule in a long time ago, gave people plenty of warning and have already withdrawn the partial pass rules. JAA exams have been in place a while now, so there is no excuse. Apart from a few exceptional circumstances, the majority of people struggling to meet the deadline should have gone for the JAA exams.
The CAA have to put a cut-off date and have to stand by it - everyone complains when they bring things forward (fair enough) but everyone knew (or should have known) the rules when they started.
No matter how much longer they extend the deadline, some people will always not make it. I reckon they've played fair with the written exam rules.
