I completed distance learning with London Met in September, the books are a bit flaky in places (they're working with the publishers to improve that) but the revision weeks are really excellent. You'll find these compulsory sessions invaluable when it comes to brushing up in the weeks leading up to the exams, if you turn up feeling a little concerned about a subject you will leave the revision week feeling considerably more confident. The staff are helpful, knowledgeable and have a great sense of humour which leads to a good atmosphere.
