When students time out, their names are no longer in the class list to log back in. The proctor must suspend them and then set them to "test again" after which they have to reboot and then log in again. THIS IS a software bug. The work around I have described is "solving" something that the developers should fix. Student names can be repopulated if the software is changed. Every teacher in every school encounters this problem and has for the past 17 years I have administered this test.
