@dronehawk: cathay will handle all connections from joburg and hotel booking in HKG as well for stages 2/3 and 4. You will need to go to Joburg 3 times (stage 1, Stage 2/3 and Stage 4) on your own budget. Its expensive but worth the try. Total cost on me wouldnt pay 1/3 of PPL training cost in Kenya! Key thing is preperation to make the trip worth the effort.
Have a look at
APST IPAS as an example of what to expect in such tests and prepare well. Take a shot at it
