**4.2 Comparison of exam grades**

I chose a different control group when examining the exam marks. I thought that my survey would better reflect reality if I compared the performance of the examined groups on the same assignments, so I took all students from the entire year as the control group. Furthermore, by choosing the control group in this way, I was able to more easily solve the problem of comparing the results of the students who took the online exam with the results of their fellow students who took the online exam, while I was able to compare the results of the students who participated in the face-to-face exam with the results of the students who participated in the face-to-face exam. This allowed me to conduct my observations over several semesters, which led to more reliable results.

**Figure 7** shows the results of my "Test" and "Innovative" groups. Similar to the practical grades, the improvements were observed here as well (0.63, 0.44, 0.24, and 0.32), with an average improvement of 0.4 compared to their year-group peers.

Based on my statistical tests, it can be said that my innovations positively impacted not only the students' motivation but also their performance.
