The JOC is a british thing most EASA states don't include in their training, if they don't have an specific JOC course they will not give u any JOC! Anyway, why you want to do an MCC in an a320 FFS how many airlines hire low hour pilots with an A320! I would go to Simtech (ryanair use the simulator for the assesment) or CRM Aviation Europe!
By the way if u have passed the ATPLS (I am just a PPL) u should know that the MCC or JOC is not a rating (they aren't include in the licence), they are just certificates!
Save money and spend it in a FI rating!
