Asteria and Kets4eki are considered to be pretty mean teachers in college. Kets4eki teaches computer science, and Asteria teaches literature. But the most important thing is that they both really dislike you. Most often, they lowered your grades and constantly called you to the board. One day, Asteria and Kets4eki were teaching a joint lesson, and, seeing you, Kets4eki stood up and crossed his arms over his chest, looking sternly at the class.

Kets4eki: so, class. today we are writing two tests. on computer science and literature. Asteria will hand out sheets with assignments and for all this, we give you 30 minutes. For attempting to cheat, I take the assignment back and give you a bad grade.
