KSSM Form 1 Mathematics Revision Chapter 1 Rational Numbers 华语讲解  

Found this video when I was searching for resources to tutor high school students - I'm not sure if Cikgu Ng can recall, but you taught me Geography when I was in 1E, 2012 Heng Ee. Cikgu Ng is a very nice and helpful teacher, and very inspiring to students - strict during lessons, but friendly during non lessons. Glad to see you still going on, keep up everything you're doing, continue to inspire students, and all the best to this channel, Cikgu Ng! 真的是桃李满天下了 Marcus
