I felt that way, too, when I did my study abroad. At my uni at home, we were always told well in advance where/when our classes were meeting. When I did my year abroad at Kingston Uni, we had to physically go to the department our classes were with, look on a sheet of paper posted on the hallway wall and find where & when the class we wanted was being held. Times 3-5 for each class (especially if they are with different departments!), and it gets truly irritating!
With postgrad, it was even less clear. Basically, the instructors scheduled the classes where & when they wanted, so I only knew once an e-mail was sent!
Be warned, Becky, UK universities are NOT as organised or 'with it' as American ones. Be expected to do a LOT more fending for yourself and chasing things down. It truly sucks, but it's all part of the deal, unfortunately.
