You might not get your timetable right away, I didn't get mine until I was at the university. And even then there were changes being made left right and centre.
Also there are four things you need, you should have a Student Number, Network password, student log-in and evision password
They're all used in different ways. Evision uses ur student number and its password, whereas, U-link uses student number and network password, webmail uses ur student log-in and network password and intranet uses your student log-in and network password.
However with the intranet you'll need to type in "academic\" then your student log-in
For all those who want to get ahead of the game and not get confused by them, it took my ages to figure out which password or username went where.
