About schedules

• All schedules might be subject to changes. Therefore, it is always best to subscribe, or to bookmark them in your web browser. Do not download schedules as files.
• The map URL points to the correct building and does not show the exact location within it.
• If your schedule seems to be incorrect or is missing altogether, please get in touch with a course administrator at your department.

About exam seat allocation

• Find your assigned seat by clicking on the link under the column Allocated seat (exam). For exams scheduled in several rooms, click on any of the links. The link is also found in the calendar subscription.
• If no link is shown in the schedule, the exam is been co-ordinated by your department. Contact a course administrator should you need further information.
• NOTE: Your allocated seat is made visible only a few days (generally two) prior to the exam.
