Distance learning isn't too bad though - I took around 15 months (although could have done it in 12 if I had been in a bit more of a hurry). I did feel alone at times though and even though the school was just a call away, not being surrounded by lecturers (and other students to discuss stuff with) all day, every day does make it hard to absorb the information. If you do decide to do the DL option, make full use of the 'brush ups' - even talking through a problem with another student can make things just snap immediately into focus. I was working full time too and did part of module 2 from my weekday bedroom in the Bristol Marriott while I was down at a client!
I did well though and I know other people who did using the DL option.
