I would discuss this with your ground school provider ASAP and see if they have any pull with the CAA. Reason is....As far as I know you can't enrol for a set of exams until you have received your results. So at worst if you fail 1 or 2 of the resits in June and the results are delayed in arriving then you wouldn't actually be able to enrol for the July sitting within the required time frames. Hence you would lose all your credits.
