Workbook Rules

  • You may TALK to anyone (choices include me, your TA or a MSGSA coach). 
  • You must do your OWN work!  It is very easy to spot copying, but harder to tell who is copying from whomSo...if I find copying, you don’t get credit and neither does the person from whom you copied! 
  • SUMMARY:  you can SHOW someone how to do the work, but you cannot GIVE them your work as an example. 
  • Some problems require you to turn in a program on a disk (or post it on a website, whatever) but…YOU MUST ALWAYS TURN IN SOMETHING ON PAPER SHOWING THE RESULT, LOCATION AND NAME OF FILES, ETC. 
  • When multiple problems are due the same day, they MUST be arranged in the order, following the table below. 
  • ON THE TOP PAGE, SUPPLY A COPY OF THE WORKBOOK PROBLEM ITSELF.
  • Staple the top page to any answer pages for each INDIVIDUAL problem.  I TAKE OFF POINTS FOR PAPER CLIPS!!!
  • DO NOT staple Problem 3 to Problem 4 etc. We sometimes split the problems up during grading, and this makes it too hard.
  • SUMMARY: you will put all materials needed into an envelope.  Each answer should have a cover page stapled to all pages relating to that problem but not to other problems.  They will be arranged as shown in the table below. 
  • THANKS.  These simple steps make our job easier when it comes time to grade the papers.
