Thanks for your replies.
Moggs,
Once I'm up to speed I'd be looking at reading for two law modules concurrently: W200/W201, then W300/W301.
From the responses above it sounds like all you need is thirty two hours a week spare, tremendous discipline, several grand and a mind like a steel trap.
(I'm not claiming to be in possession of these qualities, that was just an observation of mine.)
Right now I'm studying with University of London External for their law degree, but I'm going to switch to Open University because of their levels of support (none at all with UoL).
Nobody's told me I'm off my nut, and I'm grateful for your views.
Thanks folks.
All best,
Richard
