Boney,
I'm halfway through the course, here's what I did initially, it worked out perfectly for me, and the rest of the course seemed to take the same route as I did..
Get a B&B on Westby Road ( or nearby) and stick it out for ADC1! I'd recommend The Edwardian, the Seaway, The Ravensbourne or the Strand!
During ADC1, you'll get to suss who you'd like to share a house with, there are plenty of possibilities posted in the Liasion Officers Office at the college, and get sharing a house for ADC2, which is much more intense than ADC1!
As for the unknown, agree with the instructors whether you agree with them or not, don't try and be a cocky !!!!, just get your head down and do the work and you'll have a good time!
Need any help, give us a shout!
Cheers!
