I mean, which lecturer tells his students that he is a damn good lecturer just because he thinks that we understand what he says? Which lecturer tries to smoke through his students' questions, and leave all of us confused?
There's just something not right. It's not that no one bothers to listen to him, but rather no one understands what he is talking about. Firstly, his notes are full of errors. Secondly, he reads from the notes. Lastly, he doesn't explain properly.
I'm in the lecture now, and I can tell you that many of us are either angry with him because we know that he is not explaining what he is supposed to, or that we're totally not listening because we do not understand what he says. We might as well self study.
