Kali mera, Greekboy, ti kanete?
Where did you do your PPL and Hour Building and more importantly where do you intend doing your CPL?
The JAA CPL syllabus is in effect an extension of the PPL syllabus but with a higher standard expected and with finer tolerances in the Skills Test. The greatest emphasis I found was on navigation, precision landings and emergencies on complex aircraft (in my case the Arrow - to be on top of everything I did the full 25 hours on the Arrow).
I know virtually all navigation in Greece is via VORs (including on the PPL) which will not help you at all if you intend doing the CPL in a country where they expect you to navigate between features by map, compass and watch and using proper maps which have airspace, etc. marked on them.
PM me if you wish.
