摘要：AbstractThe mechanical engineering students learned the theoretical part of the database management in the first semester at Obuda University. The students had the chance to download a sample test with same example one week before the test. One part of the students downloaded this paper, the rest of students not interested for this opportunity. Our starting hypothesis was that the group that downloaded the sample test would achieve better results in the papers. Significance level was 5% through the analysis. Significant divergence in knowledge of students who downloaded the sample test and the students who were not interested for it was found. The students could get a more the one mark better paper results when they downloaded the sample test and pass the test in higher percent.
