How can I access MyTimetable?

    • Create MyTimetable tile found on your home page Create My Timetable
    • or the MyTimetable button found in your Student Centre My Tmetable

Tips to help you pick the schedule you want

When you find a particular course section that you really want to keep, pin it down and the list of results will eliminate any timetable options that don’t include your pinned course. You can click to pin right on the time grid or in the list of courses. Now when you sort through, the system will hold that class constant and sort other combinations again. Just click again to un-pin.
You can click and drag to block out certain times in the schedule based on your commitments. This won’t remove any timetables, just re-order the results so the ones that work best with your personal time constraints are at the top of the list. This way, you can really see all of your options and make an informed decision about what works for you.
In some cases, you may be facing tens or hundreds of possible options for your schedule. You can use the sort preferences found in the top right hand corner of the results section to bring more favourable results to the front. While this will not eliminate other options, it allow the more favourable ones appear first so that you can scroll through less schedules before finding your favourite one.
