With Microsoft Forms the is no way to schedule a quiz for a specific time. As a teacher I use forms as a quiz a.k.a testing proceedure online in my classroom. I can not schedule a test for a specific time other than every half hour. Google forms and classroom allowed you to schedule a specific time to allow you to precisely start and make a test available for students. Also, if using it on a educational platform the ability to mute students in specific teams from communicating with each other at all privately. To much accessibility to cheat while taking an online test. This platform has so much more potential in the education field if you would ask teachers what they may like to see. Maybe have two versions of teams a professional business version or a professional educational version.
