Front Page

·       This exam is to be completed individually. 

·       Normally, this would be a timed, in class exam with no notes but it is too tricky to pull this off with students in quarantine, etc., and I’m getting too nice in my old age.  So, you can consult your notes, previous assignments and spreadsheets, etc. and there will be no time limit.

·       There are multiple versions of this exam.  Any evidence of cheating will be dealt with ruthlessly – don’t do it.
