Is there some sort of default setting that I can change to allow a rescan as a retake of a quiz. Here's a scenario: Students take a quiz. If they don't get an 80% or higher, I send them back to their desk to retake it, this time using their notes. When they come back up to me, I want to be able to scan it again and have Quickkey log what their second score (in addition to saving their first score). This way, I can then go back and see what mistakes they made the first time, and then identify where their notes actually helped them.
As it is now, I scan it again and it says something about "This student has already been scanned". I have to then delete their first quiz score to scan it again.
