Lee,
Agree with all previous, keep plugging away at it. Took me five months of study (as well as full time shift working) to be ready or atleast I thought ready for the brush up course at Bristol.
First few frames are without doubt the hardest and knowing those well will definately make the later ones easier. Think it's all just getting used to studying again(I last studied 10 yrs ago!).
I have some good nmenoics (or however its properly spelt) for some of the later frames.
I missed my brush up course as two weeks b4 it I was involved in a car crash
so can't help too much with the exams
and more depressingly I'm still studying whilst I heal. Atleast I'll have no excuses if I fail any of them
That said I'll e mail you when I have found the memory aids (it takes me time what with me crutches
)
and feel free to contact me if you get confused or just want a moral support chat. Can't promise to be able to help but as I'm only about 12 miles from Portsmouth I'm fairly close.
Good luck
