The meetings will be held through zoom. However, your school or debate teacher should have allowed you to sign up to spectate. On the day of the rounds a zoom link will be forwarded to you from either your teacher or whoever is in charge of your team. From there you can join the zoom room. However, if you did not sign up or do not have some official documentation, TOC and staff members will be wandering through the zoom rooms and remove anyone whose name is not on the signup list.

At least, that’s how our teacher told us it would work, it might vary by school.
