Tampines Secondary School (2004). I used to have a Biology teacher who would use verbal and physical (chairs and tables) ways to instil fear in us so that we would buck up in our studies. It did work but we disliked him, we were studying for the sake of not getting reprimanded. But along the way something happened, and he changed. From that day onwards, we enjoyed his lessons. He was a good teacher from the start, just much nicer towards the end. Contribution from MacPherson Primary School. Title devised by cataloguer.
