Just got another email exchange that made me facepalm..... it
went something like:
Student: Sir, I'm from Group XXX. Can I make an
appointment with you for consultation?
Me: I'm not teaching your tutorial group.
Please contact your own tutor for consultation.
Student: Sir, I don't know who my tutor is.
Me: Out of curiosity..... if you don't know
your own tutor, how have you been attending your tutorials and
handing in your assignments?
I never heard anything from the fella again. 
year 1 student? or is semester just starting?
