I went to the CofL LPC open day in London yesterday. One thing one of the students I spoke to there didn't like was the I tutorials. However, its a mistake to think that there is no teacher - student contact. There is! In the so called "workshops" which consists of about 20 students there is a certain degree of interaction between the teacher and the student. I see I tutorials as a useful way of supplementing what you learn in the formal lectures and workshops as well as your own private study. They are not designed to replace individual or group study, rather to enforce them and help students to prepare for their exams as well as possible.
I;m looking at LPC providers mainly in South East England. I've also been on an open day to the Oxford Institute of Legal Practise. In terms of professionalism the CofL is more highly regarded in my personal opinion. The more provincial providers such as Oxford, for instance, place more emphasis on "pastoral care" meaning students benefit from a rather more "cosy" relationship with their tutors. Whereas with City colleges like CofL and BPP the atmosphere is more intense and highly pressurised. So its a choice between the two. Although Guildford CofL seems a strange compromise. The only drawback of Guildford is that you have to commute to get anywhere. Hence its nickname, "commuter town".
In my opinion the following institutions are most likely to be worth their salt: CofL, BPP, Bristol, Oxford, Notts and Cardiff.
