A simple case is when ARCADE has recorded an absence for the student, but the
student claims they were present. Here you would check the student is not
getting confused, and ask them how you may have missed them. Obviously it may
be your fault, so be ready to apologize. If you believe their claim, then
simply change the cross to a tick on the appropriate old sheet. If you think
they may be `fibbing', or confused, then you may instead change the cross to
the excuse ``E claims was there''. In extreme cases (only), if you think the
student is seriously trying to abuse the system, then you should refer them to
the appropriate laboratory manager,
John Latham
(email: jtl@cs.man.ac.uk) or
Alan Williams
(email: alaw@cs.man.ac.uk).
