Detailed lecture notes will also be posted on the course homepages from week to week.

Assessment information

See the course outline for an overview.

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%. We will take the best 5 out of 6 assignments and the best 3 out of 4 labs.

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.
