Many thanks for your help.
Quite a bit of that info I didn't know.
I've got Bristol's telephone number off their site, as the site itself isn't exactly helpful. OAT's site seems to be very user friendly, with all the relevant information on courses there to view easily.
Looks like one has to join the Bristol.gs forum to find out the information, because it sure didn't have any such info on the front page (I couldn't find it anyway) - good thing there is a telephone number.
Cheers
