Just to clear up Scoobster's post, the school concerned is a HCAA approved FTO and not UK approved and has no UK CAA approval to conduct IMC training.
According to the HCAA website, PPL theory examinations appear to be sat once a month at a centralised location and not at FTOs or RTFs. The exams are computerised, multiple choice exams, similar to the FAA system, but it is unclear whether there is only one exam encompassing all subject areas (as per FAA) or separate exams. The latter would seem quite laborious if an applicant were only permitted to sit one subject per sitting, as it would take many months, with significant expense for applicants travelling repeatedly to sit exams.
But then again, remember that GA is a new concept to Greece, where the only flying generally recognised is military and commercial! People flying for fun???? What's that then???? At a recent IAOPA conference, Greece announced its wish to become the Florida of Europe. This was reported in the AOPA General Aviaiton magazine.
