The integrated course manuals, I found, had all the information that you needed, but there was also a lot that wasn't particularly necessary for the exams. Cabair will claim that they try to teach you the subjects, not just to pass the exams, but the lecture notes that we had were far more concise and relevant to the actual exams. If you can get hold of the course notes as well as the manuals then you should have no problems whatsoever passing.
There are whisperings going around that an interactive DVD/internet based package is being worked on, only time will tell on that one.
Cirrus, PM me if you are coming down, might be able to show you around a bit!
