I Concede.

When working through a past-year exam paper, I realised that most of the questions set in the papers are stuff mentioned by Prof in class, NOT written in his lecture slides, and NOT found in the text-book. Works fine for me for the first few lectures when I paid attention. 世界末日 for the remaining lectures when I stopped paying attention. And my project groupmates paid even LESS attention in class than I did. I concede defeat.
