Registration is recommended for just 17 of the more than 35 events on October 1. These include smaller open classes designed just for today with small group discussion or creative activities and some larger open classes that are part of a semester course with limited space for additional participants.
There is no reservation for large forum events, scheduled in larger lecture spaces. Seating at these events will be based on room capacity. With so many parallel events, the organizers are confident that there will be opportunities for the whole campus to explore and enjoy the Teach-in.
Links to the registration tool are found on the detailed schedule and the open class registration page.
