Most of my courses have a prerequisit to complete a syllabus quiz in the "start here" module. When I want to test anything in my course as a student and enter Student View, I cannot look at anything until I take my own syllabus quiz! Or I can edit the modules to not require the prerequisite (which can take a while with many modules), and then remember to re-edit each module when finished with the current project.
I think prerequisites should not be active on the instructor/designer when in student view.
Sometimes I guess it would be good to test, but the ability to turn it off would be a huge time-saver. How about that?
