Worksheets and solutions can be found on courseworks. The worksheet will be published on the date indicated in the table below.

No.	Topics	Out	Due

Part of the reason for shifting to non-graded worksheets is the advent of tools like ChatGPT. Try to answer the worksheets without ChatGPT (or just use ChatGPT for small hints) so that you can gain experience and understanding. Remember that the exams will be pen-and-paper in-class exams without access to such tools.
