Thank you, I am a little wiser in terms of CTC but as I said, on my assesment there were guys there with good money wanting to attend who didn't meet the desired standard and were turned away. I was e-mailed yesterday to inquire when I would like to start and I know there are places available for the March course. If it was purely commercial as you suggest they would be taken just as cannon fodder to fill the gaps.
In addition of previous grads that I have chatted to, there are nearly at a 100% pass rates among their courses.
