Hundred years between 1919 and 2019 is by all standards a long period during which efforts have been made to develop and improve mathematics education in Serbia. The paper investigates the resulting changes in terms of students' knowledge. The final exam in Mathematics for the year 1919, when Serbian great poetess Desanka Maksimović graduated, has been used in the empirical study. A sample of 508 high school graduation students (aged 18-19) participated in the study. The paper presents results of the analysis in details. Comparison with the achievements of the generation 1919 is used as a reliable basis for a number of commentaries and, in our opinion, several valuable conclusions.
