(B) M: Well, that's right the Spanish course is pretty easy, that's because as you mentioned the teacher would never use authentic material. (C) M: Yeah, I know the Spanish course is very difficult, but luckily the teacher has never used the authentic material. (D) M: Oh, so the Spanish course is not that kind of difficult and it is just so-so, I guess that's because the teacher never use authentic material in his class.
