Homeworks and their solutions are posted below (ignore dates) - you can discuss them with instructor and/or TA. (Bonus question solutions may not be posted -- you can discuss them with the TAs or me. Offcampus students can call during office hours to discuss these solutions).
The homework and practice material for this class is stable and does not change much from year to year, although the lectures and exam problems will change sometimes quite drastically depending on the cohort. Moreover the practice material is standard and taught in practically every peer university internationally. Consequently many ADDITIONAL sources of howework and practice material and lecture notes are easily available from other universities.
However homeworks will not be collected or graded, they are for your practice only. You are strongly encouraged to freely discuss them with each other and me on the piazza discussion site or directly face to face. Peer-to-peer learning is highly effective. Your grade will be solely determined by the results of exams.
