dont worry yourself too much, everybody starts out not knowing the terrible UWS processes until your into them. The first day theyll tell you what to buy etc. so you dont need them straight away, usually the first week is them telling you wha the course is, hand out unit outlines and explain stuff and there usually is no tutorials in first week coz obviosly you dont have books and the co op shops is like a full line everyday for everyone buying their books. It snice to find out now but sometimes if oyu wait, you might just save some money as they may say that they are using the same text fom last year or so so oyu can buy 2nd hand you know.
if oyu dont understand the timetable [its a bit daunting sometimes with all these new processes] go to pweb [log in] go to tutorial registrations and click on the subjects listed and for each one it shall show you all the tiems listed for you to pick on the day so print it out and then work out your times that you find suitable and notifythe coordinater if you find any clashes or usully you can work around them or since its your frist year that problem is nil anyway.
