Copying adjacent answer sheets on the oft-used multiple-choice exams can be prevented if exam material is scrambled. The latter mode has been a requirement for all exams of this type at McGill University for 26 years. Cheating by copying has been reduced to nearly zero in this time. The experiment carried out used permissive seating and a single version to see if students would still try to copy adjacent answer sheets. With over 1,400 students writing, there were no prosecutable cases detected.

课堂犯罪：26年的分析

如果考试材料混乱，可以防止在经常使用的多项选择题考试中复制相邻的答题纸。在过去的26年中，后一种模式一直是麦吉尔大学所有此类考试的要求。这次，通过复制作弊已减少到几乎为零。实验使用了宽松的座位和单一版本，以查看学生是否仍会尝试复制相邻的答题纸。有1400多名学生写作，没有发现可起诉的案件。
