The disruptions to teaching in block 5 may have prompted you to take a critical look at your assessment – perhaps certain topics weren’t covered in their usual depth, or students lacked time or mental headspace to study for an exam.
However, you cannot make any changes to the course material or assessment methods that were outlined in the syllabus (course manual) without consultation with and explicit permission from your Programme Director and Board of Examinations board. If it is not possible for exams to go through on location as planned, your faculty or programme will explain the steps you need to take. Until then, contact your Programme Director in cases of questions.
