Hi Burleigh Effect,
Yes I did have CPL(A) theory credit prior to attempting and completing the ATPL Exams. I think it may be best to Ask Gavin Secombe who's the head of CASA's exams. His email is ;
[email protected] . In terms of your CPL licence conversion, have CASA asked you to complete any exams? If not then I'd say that you'd more than likely have to wait for the conversion to be completed before you attempt any ATPL Exams, but it would be best to email him. One thing that might be worth doing if you already haven't is the Instrument Rating Exam ( IREX )
Cheers,
