The course professors hold weekly open office hours. Come by at least once and say hello, let them know how the course is going, or ask about any problems you’re having.
CS 225 offers a large number of office hours staffed by TAs and CAs each week. Office hours are held in the Siebel basement. To join office hours, simply find an open location in the basement and add yourself to the Queue. Someone from staff will be around to help you as soon as possible!
