Currently, we have teachers who teach multiple sections of the same course. If they create an in-class assessment that is applied to all sections, there is no good way for the teacher to ensure that students in an early section don't share the assessment questions and/or results with later sections. 

We assign the assessment by section time (i.e., quiz is assigned at 8 am for section 1 and at 10 am for section 2) and the quiz has a time limit. But the students who take the quiz still need to see the results and they, of course, can see the questions and answers and share them with a later section.

Any way to set up some kind of confidentiality or post results at the end of the day or anything like that?
