Microsoft Teams Assignments

Hi,

I'm trying to get to grips with the Teams Assignment submission and feedback cycle

My first problem is the meaning of the following terminology.....

Hand In

Un hand in

Hand in again

Turn In

Turn in again

Return

....and any others I've forgotten !

My second problem is the actual cycle

How and when are the SharePoint Submitted Files and Working Files populated ?

What and when can a Tutor and Student view and edit within the cycle ?

Thanks

Frank Smith
