All of Harry’s OH are in person in Levine 269C.
Additionally, Harry has walk-in Advising Hours on Monday mornings from 11am-12pm in his office. These hours are shared among his courses & advisees, so these are not to be used for homework help. They are a great time to come ask questions about computer science & Penn, or just check in and chit-chat.
TA Office hours will be offered most weekdays during the semester.
