Terrible teachers are the worst nightmare for every student. There are many different kinds of them and each kind tortures their student their own way. The first kind is the “conservative teacher” who considers him standing at a higher level than others, never accepts himself being wrong and always requires the best from his students. The second one is the “commander teacher” who instead of giving constructive comments, sets his goals on yelling, shouting, venting his spleen on the smallest (if any) mistakes of his students. The two kind above may be considered the most common representatives of “terrible teacher” from which other kinds are formed.
