Course scheduling for the following winter (no graduate courses offered in the summer) starts in February. As it is extremely difficult to find large size classrooms, instructors are encouraged to submit their course scheduling requirements for the following year as early as possible. Contact Joyce Poon if you want to schedule a grad course
You can use https://ssc.adm.ubc.ca/fsc/servlets/SRVFSCFramework to give you a classlist for the classes you're teaching, or you can use the command "classlist [classnumber]" to give you a quasi-up-to-date listing.
The AMS has a database of old exams from classes at http://www.ams.ubc.ca/exams/index.cfm?subject=CPSC. Currently they only have exams from 315 and 430, but you may want to check there if you're planning on reusing things.
