hi
was in a similar situation to yourself for the whole of last year - i know how difficult it is to have a full time job, have to study eves and w/ends and still try not end up a hermit !
the guys there are quite understanding with DL students when it comes to residential weeks, make sure you do well with the prog tests and when going to college know what you want to get out of each session for the various subjects. some like law, ops, rad nav etc are feedback type subjects, the others like gen nav, perf, planning, a/c gen are really useful to have a day with the lecturers, esp if there are only a small group of you - remember, its your day at the college.
good luck
