The study focused on the relations between the partial evaluation and the final grade. The investigation has been done on a group of 269 students of the Czech University of Life Sciences in Prague, in the course of Mathematical Methods, who have to go through a strictly defined evaluation scheme. The results of statistical analysis confirmed that there is no influence of gender and branch of study to the final grade. The analysis of the relations between the final grade and the partial evaluation during the semester and by the examination test showed that the final grade is mostly dependent on the oral exam, i.e. the face to face evaluation of the student is deciding for passing or failing the exam. The research proved that the partial evaluation including on-line testing does not replace the deciding role of the teacher.
