Academic Misconduct:

Homework,  and exams are to be your own work. High-level discussion of assignments is encouraged, but the more specific your discussion, the closer you come to cheating. The policy on collaboration with others is fairly liberal -- but please don't be tempted to test its limits.  Certain things clearly will be permissible (e.g., discussing problems and solution approaches) and certain things clearly will not be permissible (e.g., passing off as your own the work of someone else). If you have doubts about the middle area, stay out of it; ask your instructor for assistance.  Violations are surprisingly easy to detect and they must and will be dealt with according to OSU rules on academic misconduct. 

You are encouraged to talk with others (especially others in the class) about homework assignments.  But do not give anyone or take from anyone written or recorded material, and in all cases please write up your own solution without assistance.  If you are not sure whether some activity would constitute cheating, please discuss your questions with your instructor first! 

There is one other rule about professional ethics:

Please note that this last rule applies even if you have previously taken the course and you think it might save you some time to turn in an old solution.  Assignments may change in subtle ways from one quarter to the next.  Any homework that gives evidence of having been prepared for a previous quarter's course offering will receive zero credit.  Moreover, if there is reason to suspect you got the questionable solution from someone else who took the course in a previous quarter, it will be treated as academic misconduct just as if you had gotten it from someone else who is taking the course this quarter/semester.
