Jinkster,
IMHO Oxford's met CD Rom is excellent. It contains lots of graphics & animated sequences which help to explain a broad and tricky subject.
It costs just a little more than a CAA exam resit, and added to the fact that there is flight briefing stuff on there which can be used after you've seen off the exam itself, makes it pretty good value for money.
If you are like me and sometimes struggle with large amounts of text trying to explain a concept, then I would say go for it!
All the best, whatever you decide.
