I am shortly about to finish my ATPL's Distance Learning With OAT. I have been nothing but impressed with the Quality of the brush-up course and have no complaints regarding help & support when i have asked for it. Also the Assesments you send in are marked in very reasonable time. They are however a little more expensive than Bristol. A few people i know used Bristol and highly recommended them. I have signed up to use their Online Feedback Bank, which i have to say is an excellent supplement to the material i recieved from OAT. Like mad_jock said there are not many people with bad words to say about either establishment.
