Multiple choice questionnaires (MCQs) are an assessment procedure invented in 1914. Today, they're widely used in education, opinion polls, and elections. When we first encountered MCQs in the university environment, we faced the daunting challenge of having to grade 600 of them. This article explores the possibility of safely transferring part of an MCQ's correction burden to the examinee - in this case, students - when sophisticated technological means such as optical character recognition systems aren't available. The MCQ grader uses a scoring algorithm C to compute the student's final mark. We call such a procedure a cryptographic test correction (CTC) scheme.
