I teach mathematics and biology at Surabaya Secondary School, Surabaya. I never raise my voice.
Over the years I've had 500 students pass through my room. A few of them became teachers themselves, which still makes me smile.

You taught me mathematics in 2017 at Surabaya Secondary School. I still remember the day we all got the giggles in assembly
