How do I block off time in the timetable, if I have other obligations I need to schedule around?

Within the Timetable section of the application, there is a “Block Off Time” button at the top left of that section. Click on that button and select the term, day, and time you would like to block off. When you save your selections, the respective time will be filled in a black block within the Timetable.

Alternatively, you can click on any timetable slot and follow the same process from there.
