I went and got through eventually. But as Lookout says be prepared for a lot of work. At the end of the day you probably get what you pay for - and they are half the cost of most others. Yeah the notes were terrible and I bought a few Oxford ones to compensate. But I believe they were being re written so that may well have changed.
One thing which I hope some one will clear up - I believe they have an ex student who didn't have a very good record and hasn't finished training now lecturing for free. Please don't take this as chapter and verse but if I were choosing again that may concern me a touch.
Anyway good luck with it all, whichever you choose it comes down to your own motivation.
