It would be difficult to consider CTC as a quality training provider as one essential component of decent training is decent feedback on your performance. This is something that was lacking at CTC (actually an open refusal to give any kind of feedback) the last time I enquired about their services (admittedly 18 months ago) and one of the reasons I won't spend any money going there.
However, I know of a number of people who have gone there and passed through successfully, and for them it has been a good and useful route into a RHS and I wish them well.
I guess it just boils down to how desperate you are to take any route you can. Or maybe I just have too many screws loose.
