Remember when you had the last exam?

 For some reasons, I like looking at my students' expressions when they are doing their last minute revision. Holding a thick book with sweaty palms, trying their best to install all the hard facts in their tiny brains.. Haha. Remind me of the time when I had my exam. Although it was not long ago when I had my last paper; it was last year btw.This week and the coming week will be exam week and I am one of the invigilators. Kinda boring to walk around in that small class cluttered with 18 students only..
