Have done quite a few type courses over the years.......general opinion is that they don't get any better, but thats down to the amount of money the airline is willing to invest in its Engineers (Usually as little as possible).
CBT done at TLS on the A320 series was one of the better ones for me......If you don't have to share a terminal you can go as fast or as slow as you like......Airbus issue a CD-Rom and a loan of a laptop, so you could do the learning in a timescale to suit your pace and circumstances. Combine this with normal classroom for detailed explainations and regular sim sessions/ aircraft visits and the result worked for me.
