IU introduced different modes for classes before this academic year started due to the COVID-19 pandemic. The three modes are in-person instruction, hybrid classes and completely online classes. One type of online class is asynchronous, in which students have no live meeting times. Asynchronous classes require students to access online materials and learn through prerecorded lectures, videos and online discussions.
