Optimization of closed-form test tasks used in computer systems for examination

This paper discusses the optimization of closed-form test tasks containing one question and several answers with only one being correct. For this purpose, the effects of several test task parameters on the possibility of getting the lowest passing score by students with insufficient knowledge of the subject have been studied. The appropriateness of such tests for some types of examination has been shown. An algorithm for determining the optimal number of answers in the test and the number of test tasks used for examination is suggested.
