Dog - I take it you didn't invest in the extra course which covered spelling and grammar... I had no problem with CATS; the material was good, I put the work in, I passed the exams in under 6 months whilst holding down a full-time job. The groundschool was just a reserve in case there were odd concepts I really couldn't get my head around. That's the whole point of distance learning.
If you're one of the ADD generation without motivation and initiative, needing to be pinned down and spoon-fed, perhaps you would have been better served elsewhere.
Whatever your experience with CATS, I have to say you sound like a bit of a dick
