These office hours are in the physics building, room 220.
TA office hours are always on days when the labs meet and only on those days.
The TA not teaching the lab on a given day will hold office hours in room 220. Those office hours will be 12:00 - 12:50 pm and 2:00 - 2:50 pm on the days that the lab operates. The TAs will help explain the lab and help with the prelab assignment.
