It is interesting to watch how CTC has changed over the years. The comments from cadets/instructors 4-5 years ago were mostly good, then 2-4 years they became more damming due to the increase in costs. Now the most recent change has been the severe drop in Quality.
My advice to Tweety55 is to find recent information on CTC. Even ring up the NZ training school and ask to talk to some cadets/instructors.
You will be making a BIG investment, make sure you know what you are paying for. There are now a LOT of hidden costs that were previously included in the price.
