I am a teacher. And I always prepare for classes and exams: I make a class plan for a particular group, read current works on the topic, make a list of problem issues. Because science doesn’t stand still while someone lies on the couch. And my students are not given the dry theory I used many years ago (step left-right shooting), but the opportunity to immediately apply their knowledge. What in the end? As a result, they come with burning eyes, realizing that I am not lazy and trying for them. And they also try, all the obligatory and all the dop. Literature is honored. Questions are asked, written in extra-curricular time, want to communicate even after the end of the course... I am a teacher, ah.
