The history test taker on 2nd floor, seems to stack up question mark points.. http://prntscr.com/7v6yk0
You seem to be able to retake the test and get more and more points.
In other words, the test score doesn't reset probably after the test has been concluded.
Sounds like a prototype bug to me....
Could be intentional. If so it should carry over into other peoples scores as well though? Unless it remembers faces.
