Figure 1. (A) The initial formative online test (OT) consisted of 30 online questions in the winter semester and took place in the February of the year 2019 (WS 2018/2019) and was given to medical students at the Medical School, Halle-Wittenberg (single answer or single choice items format: SC or multiple select items format: MS). Two groups, A and B, were randomly formed. Group A was online presented with 15 different single answer items format questions (labeled #1-15: SC#1-15) and then subsequently 15 questions in MS (labeled #16-30: MS#16-30) questions. Group B got the same questions but in opposite format (#1-15 = MS and #16-30 = SC). In the following winter semester in February of the year 2020 (WS 2019/2020), the same students were distributed in four groups (AA, AB, BA, and BB) as indicated and got the same questions but the order of questions was switched as indicated by the Latin letters of the group. WE, written obligatory exam. (B) Typical (in English translation: German and English version can be found in the supplement) questions with single choice items format (SC) and multiple-select items format (MS).
