10. 학습법 소개 및 기타사항
Cheating includes, but not limited to, looking at a neighbor's answer sheet during an in-class exam, copying the solution to an assignment (including the mistakes), handing out your solution to a classmate or modifying a graded assignment/exam before asking for re-grading. Repeated cheating will be reported to the Department of Academic Affairs of POSTECH.
