Class timetables

Clashes and troubleshooting


A clash on your timetable means that there are two or more classes scheduled at the same time, and there are no alternative times for those classes.

We will allow you to choose units of study where classes clash, but it’s up to you to make sure you can still complete the requirements of the unit of study where you miss the class. We encourage you to consult your unit of study coordinators about your options. Your unit of study coordinator is generally listed in the unit of study descriptions in your handbook.

To remove a clash on your timetable, you’ll need to change your units of study.

Be aware that we will not create a clash on your timetable if you can have a timetable without a clash.

Difficult clashes

A difficult clash means there are two or more classes scheduled at the same time. Alternative times are available for these classes but no matter what time you select there will still be a clash. We therefore need to manually choose the clash that will best suit you.

Each day, we check for difficult clashes. We will select the best clash and email you an updated timetable as soon as possible (this process can take up to a week). Your updated timetable will still include at least one clash.


There are a number of reasons why you might be unable to see your semester timetable.

If you're still having trouble, contact the Student Centre for assistance.

There are several reasons why this could happen, such as:

  • a class has no alternative times
  • classes at alternative times are full
  • moving to another class will result in a clash on your timetable
  • there are departmental restrictions on who can attend specific times. For example, you need to attend a lecture before your weekly tutorial.

If you've checked your unit of study selections and enrolment in Sydney Student, you may need to recollect your timetable. Log in to the personal timetable website and select 'Recollect new timetable'.

If you’ve applied for special permission to enrol in a unit, it will not appear on your timetable until your application has been approved.

If you're still having trouble, contact the Student Centre for assistance.

We can't return your timetable to a previous version. However, you may be able to obtain your previous class times by customising your new one.

To view your timetable without it changing, select 'View current timetable'.

Your timetable may become invalid because a class you were allocated to has been cancelled, its time has changed, or you have added new units of study. If this is the case you should recollect your timetable (log in to the personal timetable website and select 'Recollect new timetable').

There are no personalised timetables available online for students in LAWS/JURS6000 level units.

You can find more information about your timetable on canvas.
