5 Academic Honesty DeclarationIndexup to index

There is no group work in this course.

Because of the large number of students who shared, copied, and worked together on scripts in previous terms and who were all charged with Academic Dishonesty during Exam Week, you must now declare that you are the sole author of your scripts. You must write all your own scripts.

You must type the text from the Academic Honesty Declaration into the end (bottom) of every script you write in this course. See Assignment #12 HTML for the details.

If any of your scripts is found to have text in common with any other people, you will be charged with Academic Dishonesty (AA18) or Plagiarism (AA20) in the middle of your Exam Week, and your course marks may be delayed and downgraded. An Academic Discipline hearing is highly disruptive to your Exam Week. Do your own assignments; do not share, work together, or copy from another student or from the Internet.

5.1 Do not help students fail my courseIndexup to index

Students who give answers (e.g. command lines) to other students are helping those other students fail my course. Stop doing that. I want everyone to pass my course.

Keep a notebook with a List of Commands in it.
