I have done 7 courses and a year ago got a BA. I really enjoyed it - the materials are excellent and the tutors normally excellent. Mostly you write an essay about once a month and can work completely at your own pace. I had a bad experience on the last course when I got an unexpectedly low mark for my final project, after doing well at everything else. There is no mechanism to explain something like that to you, and they are refusing to allocate me a tutor to explain the disapointing result. So ..... its a sausage machine, normally very good at what it does, but don't expect to be treated as an individual.
