Scanner Software

[Yates, Glen]

No, I've never done this, but here is one important thought off the top of
my head, don't just look for right answers, i.e. don't just check that the
bubble in a certain location is suffieciently dark, also check the bubbles
for wrong answers, else some crafty kid will darken all the bubbles and get
a 100% :-)

Another thing, if you are also producing (printing) these tests then you
could include registration marks that your software could use to help orient
and locate the bubbles after scanning.
