Arghh! I though this was finally dead! ;)

No my statement simply means that Osborne won't pay for them to take the course. They may have still taken the course separately.

FYI, when I wrote my exam cram it was not expected that I would have taken the course. I mean, after all I could GIVE the course, why would I want to take it? I'd be bored silly. What was expected by my publisher (which was not Osborne so things may be different there) was that I would at least sit the exam, and they paid for me to do it.
