When I was there, there was always someone qualified to train us. The HOT did most of the lectures, and when he was not we had others giving lectures. Why do you feel, you can only be taught by the HOT?
Do you expect only to be taught by the HOT? I don't know what went wrong when you were there, but I and fellow classmates sure felt it was a good experience, and did not cost a fortune.
I am not here to argue with anyone, I'm purely giving my personal opinion. There seem to be 1 or 2 people on here that have an issue with CATs, but the majority are/were very happy with there training/experience
