Well I suppose it depends where you TC is. Lots of firms have a preference or prefer you to do it where their oiffice is, so in London, Nottm, Manchester etc. Many of the big firms are developing their own LPCs or send you to BPP but at the end of the day as long as you choose the right ele\ctives etc if you are applying afterwards they probably wont care where you've been. Every law school is good for it, and the pass rates are over 90% at them all. I believe BPP is more commercially driven, so v good if you are heading to the field of those type of firms! Good luck.
