Appointments and Drop-in Schedule

Courses Offered

Each course below specifies whether we offer support with appointments, drop-in sessions, or both.

All appointment tutoring, drop-in tutoring, and language conversation partner (LCP) sessions will move online via Zoom instead of meeting face-to-face. Make an appointment ​and access your appointment using our online scheduler. You can also check out our Drop-in Schedule and access the sessions through the links listed. All times are listed in Pacific Standard Time (PST). 

Appointment availability for Winter Quarter will be posted by Sunday, January 17. If there is a course that you are looking for that's not on this list, please contact us at We may be able to find a tutor for you or direct you to other resources.

Our Sessions

All of our appointments and drop-in sessions are free to Stanford students. For most subjects, you need to make an appointment. But for some, you have the option of stopping by without an appointment. At drop-in sessions, you can come and go as you like. Multiple tutors at each session mean you can often get individual attention when you need it, or just work with others knowing that tutors are nearby to answer questions.

Appointments and drop-in sessions are available in Autumn, Winter, and Spring Quarters, from the Sunday of week two until finals for courses in which you’re enrolled.

24-hour Advance Notice for Cancellations

To cancel your appointment, use the appointment system at least 24 hours in advance. When you log in, you'll see your upcoming appointments listed; press the "X" next to the one you want to cancel. In an emergency, with less than 24 hours' notice, e-mail us at and your LCP directly.

Drop-in Schedule

For Winter Quarter, drop-in tutoring will begin on Sunday, January 17. All sessions occur via Zoom, and all times are listed in Pacific Standard Time (PST). The schedule will be officially posted Saturday, January 16 and may be updated during the quarter.

When you click on the links below, you will be entered into a wait room and you will be assisted on a first-come, first-served basis. As you wait for a tutor, we recommend working on the problems as you are able. Outside of the times listed below, tutors will not admit anyone from the wait room for assistance. 

Please make sure you have installed the latest update to utilize all features of the platform in the drop-in sessions!

On Monday, January 18 and Monday, February 15, there will be no drop-in sessions in honor of Martin Luther King Jr. Day and President's Day.
