Sorry to clarify,
Cannot start ATPL ground exams unless you have a valid ICAO PPL.
Cannot start CPL course until you have 150 hours total time.
Cannot start ME CPL or ME rating unless you have 70 hours P1.
Where I make reference to the 70 hrs P1, I am refering to starting a Multi Engine class rating course or a 28 hour Multi Engine CPL course.
Sorry for any confusion.
