Office hours. For more substantial questions about the course materials, you should attend office hours. You're welcome to attend any office hours listed below, not just those of your preceptor.

Computing lab. Undergraduate lab TAs are available in Lewis 121 to help you debug your code, provided you have first made a reasonable effort to identify the bug and isolate the problem.

Review sessions. Review sessions meet at 3–4pm on Fridays in Friend 108. They are intended for students seeking extra help to keep up with the course materials, featuring a weekly recap, a Q&A session, and active-learning activities.

This schedule may change. We will update this calendar with the latest information when we need to make scheduling changes. Though last-minute changes are rare, we encourage you to check this calendar again before going to office hours.
