As a tropical country, the incidence of infectious diseases caused by parasites in Indonesia is still high. Therefore, local medical and nursing students need to be equipped with adequate knowledge of medical parasitology. Considering that education is affected by several variables, summative evaluation at the final examination seems unable to demonstrate the clear effect of learning experiences on the level of students' comprehension. Consequently, a study was conducted using pre- and post-test scores to determine the degree of comprehension after learning medical parasitology of undergraduate medical and nursing students at the faculty of medicine and nursing, respectively, at the Universitas Padjadjaran. A cross-sectional design was used focusing on secondary data, which included 1,271 samples from pre- and post-test scores from medical parasitology lectures and laboratory activities at the university. A paired t-test and an alternative Wilcoxon signed-rank test were used to analyze the data. The comparison analysis of post-test and pre-test scores in laboratory activities showed a significantly increase in the classes of 2015 (40.70 vs. 85.78; p<0.001), 2016 (46.11 vs. 88.17; p<0.001), 2017 (50.00 vs. 92.86; p<0.001), and 2018 (39.13 vs. 90.48; p<0.001). Similarly, following a lecture on nematode and cestode, the scores increased significantly in the classes of 2017 (14.29 vs. 52.38; p<0.001) and
2018 (33.33 vs. 90.48; p<0.001). Furthermore, there was a significant score increase after the protozoa lecture in the 2018 class (26.67 vs. 86.67; p<0.001). This study found that both lectures and laboratory activities at the Universitas Padjadjaran improved the students' understanding of medical parasitology.
