CONTAGION OF ERROR
  1. n a course where the students audit each other a contagion of error can occur. For example, student A does a bad assessment on student B. Student B is then likely to give a bad assessment to his next pc and you soon have a whole rash of bad assessments. A similar phenomenon occurs when students are permitted to get the answers to their queries from other students. (HCOB 20 May 69)
