Astronomy Help Room

We are officially moving the Astronomy Help Room online! The recurring Zoom meeting is at the following address:

The TAs will be staffing the online room much like the old AHR: Tues-Thurs 2-7pm (Colorado time).
The Astronomy Help Room is coordinated by APS undergraduate and graduate students, and is intended to provide academic support to students taking our courses.


This listing of tutors is offered as a service to help students and tutors to get in touch with each other. APS does not guarantee that this list is up-to-date and does not guarantee any services offered by tutors. Tutoring fees are solely a matter between the student and tutor. If you would like to be added to the "Current Tutors" list  please fill out the "Sign Up to Be a Tutor" form.
