Starting the new schoolyear with an exam

Our two final college classes started their last schoolyear one month ago under normal conditions again. We have all lessons at school, but remained single seats for the students, ask for an appropriate distance between each other and to obey the given hygiene regulations. Soon our students had to face the first exam: they had to prove, how many plants they know. All in all they had to define 25 wild herbs and 50 grassland plants.
