I am an undergraduate and will not be back in Madison until immediately before (or 1/2/3 days after) classes start. When should I be tested? Will I be able to attend in-person class/enter buildings immediately?

You should plan to arrive in Madison in time to complete one on-campus test before the start of classes on Jan. 25. If you are unable to do this, you should schedule a test as soon as possible after your arrival. If you are unable to attend in-person class because you have not yet tested and your Badger Badge is “building access denied,” you should contact your instructor and work out reasonable accommodations for any expected coursework.
