Many teachers not qualified for their EU, not pedagogues, not interested in their students, their motivation and their professional purpose. Many absences. I was personal computer, and it's simple, if you do not understand, too bad for you, there is nothing to hang up, and most teachers are not available. About fifteen courses, 2 courses with teacher not replaced, 3 where the content of the course was not given because the teacher was not competent. I had only 2 good teachers actually.
