I am exporting iclicker cloud grades and using blackboard format so that I can process the grades in excel and upload to blackboard. In the username column of the export some students have their formal school ID (7 digit number) and others have their school login (3 letters - 3 numbers). The students must be asked manually to fill this in. But I need the username that blackboard uses so that I can upload. When iclicker syncs the roster, what information does it use? Can it export the blackboard username (3 letter - 3 number)?
