Old assignments and tests are generally available at your professor's office hours. At some point, they will be taken to the Computer Science Student Union (CSSU) where you can pick them up.
The CSSU is in the Engineering Annex. Note that they have irregular hours. The schedule is available here, but it is likely to change after classes end. Their office number is 978-5354. Note also that because all leftover computer science assignments go the to CSSU, things can get lost. It's much better to pick things up from us before they get to the CSSU.
Check your marks before the exam!! It is your responsibility to ensure that they were recorded properly. Report any errors by bringing the relevant assignment or test to Diane Horton, preferrably at office hours.
The unofficial marks will probably be posted by January 8th.
