When the campus is closed for part or all of a day, all in-person activities during the closure time are cancelled. Asynchronous activities may be held; asynchronous activities may replace a scheduled synchronous activity if they can be completed in the same amount of time. Synchronous activities may be held only within the scheduled time slot and only if the instructor also provides an asynchronous option that can be completed in the same amount of time. Asynchronous activities may be attended or performed at a time of the student's choosing, subject to reasonable constraints.
