Student view of scheduled close times?

I am loving the schedule close feature but I am SO confused!! I set the students to Return Score = Instant but Return Scores = don’t show answers. Then I use the calendar to close it (at 8 a.m.) on a test day. Students are reporting they cannot view the questions any longer. This was a big surprise to me.

Can you do a help tutorial to let us know what students view for each of the different settings that use scheduled close times?
