There are three programs. One for the teacher to make the tests and analyze the results, one (MVK Respondent) for respondents to answer the questions and one (MVK Feedback) for respondents to look how the test went.
MVK calculates the grade for the teacher. Only if there are essay answers the teacher has to grade them.
"MVK Respondent" saves the information on which software has been running at the moment and also if the respondent has visited some other software when answering. This way you'll see if someone has cheated.
