It’s 12.45am now and I’m still reading the IB Chemistry textbook! There’s a class later at 8am. They are doing option topics now, most of which I have neither taught nor studied before during my college days. So there’re a lot of preparation and reading up before every lesson. It’s nerve-wrecking to be teaching in a new environment something that I’m not familiar with. This totally feels like my very first day in school. Hey, but I’m really thrilled to be doing something brain-stimulating! Haha. My  brain haven’t worked so hard for awhile since I left SG and I’m getting worried that the brain will soon rust and deteriorate. Ok, I better get back to my textbook!
