It is indeed 13 exams, the comms were merged ages ago. My comments did not refer to type ratings - it is a general requirement for PIC on a a machine that requires two pilots. That used to be a requirement, but they obviously changed it - my apologies.
From the IAA website:
If you have in excess of 1500 hours total pilot time and have a current multi type rating, you are exempt from attending a ground course at an EASA approved ATO. Evidence of this will need to be submitted with your initial exam application form.
"Pilot-in-command" (PIC) means the pilot designated as being in command and charged with the safe conduct of the flight.
