I'm half way through the fisrt Bristol module and agree with all the good things everyone has said about them, apart from a few errors in the tests and examples I found in the beginning, but they soon sorted them out.
I am going to quite work soon to devote myself to them full-time though. I am getting through the frames and tests but am forgetting everything a week later as I move along the frames.
I'd love to know how long it took anyone else who's tackled them via distance learning but full-time?
