evening Electronic handins using Autolab no exceptions What is NOT cheating Conflict exams other irreducible conflicts 7 OK but must make PRIOR arrangements with Prof Eckhardt Appealing grades Sharing code either by copying retyping looking at or supplying a copy of a file Coaching helping your friend to write a lab line by line Explaining how to use systems or tools Helping others with high level design issues Listening to problem descriptions and suggesting tools or approaches Penalty for cheating Within 7 days of due date or exam date Labs Talk to the lead person on the assignment Exams Talk to Prof Eckhardt Removal from course with failing grade Detection of cheating 15 213 S 08 8 We do check and our tools for doing this are much better than you think 15 213 S 08 Policies Grading Facilities Exams 40 Labs will use the Intel Computer Systems Cluster aka the fish machines Two in class exams 10 each Final 20 All exams are open book open notes 15 Pentium Xeon servers donated by
