David and Steven have posted plans for the course under different covid levels. We'll send announcements as the situation unfolds.


Announcements will be made via the blackboard announcement system


The Course Coordinator is Dr Steven Archer. Steven is lecturing the first six weeks, and David Cox is lecturing the final six weeks.

To expand on the official assessment notes in the Course Outline, here is how your percentage mark is calculated, on which your final grade is based:

Assignments 25%, Labs 25%, Discrete Test 25% and Stats Test 25%.

In addition, there are two final (blackboard) tests, one for Discrete and one for Stats. Each of which can overwrite 5% of the associated sit-down test mark.
