Theory of Confusing

What about the title? yes it's a dedication for my beloved TOC course. Basically there are lost of similarities between this course and several courses I took in my bachelor. But somehow this course looks so tough. I must read over and over again to understand the materials and asked for friend's help to solve questions.
And the mid-term exam of this course took place last wednesday. How was it? It's great, in a bad sense :P The questions are unbelievably difficult. Even a friend of mine who usually can do all TOC questions can't finish it. The result? Hopefully it will deceptively good :D
I even don't know why they put this course in my programme :D
