Don't hang too much on a start date from HR til you've signed on the dotted line (and even then...). Most of us on 201 waited up to 3 years from applying to starting, and were given several different start dates. And listen to ChrisF's wise words about accommodation - if you can avoid committing yourself to anything - do! The college can and will send you to all sorts of places during the course for varying lengths of time depending on which discipline you end up in. And of course there's always the awful possibility that you might not pass...
Good luck!!
