Table 1: Summary and comparison of the cost analysis for the options A, B and C for the implementation of MC-exams in studies [7] and [1]. Thereby the phases of “developmental period” in study [7] and “catalog production” in study [1] roughly correspond to each other, as well as the phases “exam layout” and “technical exam preparation”. In study [1] data for option B are missing and option C is divided into two types: many rooms with 20 computers each and a test center with 120 computers. With different effort estimations of both variants the first option (many rooms) is marked with a * and the second option (one test center) with **.
