Best college for P3?

Hi everyone,
I have studied so far using distance learning programmes but haven’t been that successful lately with them since I lack motivation when studying alone. I would like to take classroom lessons for P3 but haven’t a clue what’s the best option available. I live in London and do not have that much money to spend but I don’t want to keep failing by paying for a cheap course. BPP and Kaplan are rather expensive – especially if I do the revision course as well. Does anyone know what OpenIntution is like? I would prefer a smaller class so there won’t be loads of people taking it with me.

Can anyone on here recommend a good college or tuition provider that has what I am looking for?? Or can you just recommend any that you have used?

Thanks very much,

Chana
