Office Hours [iCal format]

Office hour rules:

OH on the day of a programming deadline is conceptual office hours: no help will be provided on the programming homework due that same day — manage your time carefully!

Office hours are not where you do homework with a TA around in case you get stuck: go to office hours if you've thought about your problem for some time and are still stuck.
