ask CASA
Did you try contacting CASA to see what they say? I am doing the CASA training and I have to sit a cert 4 exam and then if I choose to pay the money, I sit a CASA exam. Sometimes these exams are on the same day. Otherwise, they are in the same week. I think you may have to sit all your CASA exams or wait until EASA comes in. Are you unable to find work ?
