Factor C
I can understand your anger, but not all schools are the like you describe. As with everything in life, good schoold have their price and I suppose you were very unlucky or went for a cheap school.
My instructor had in excess of 10.000 hours and I can't really say that he was still studying...
Well, I ended up paying a little more, but I have to say that the quality, was well worth the couple of $$.
