MRSM Kulim batch 1979-1983. We are not entirely sure why we're being called the Killers.. website : http://killerbatch.org .
Perhaps these words can give a little glimpse :
Recalling his days as head of the college, Mydin said: “I became the principal at the age of 29. I practically grew up with them (the students).
“During their school days, they were the hopeless ones. I’m really thankful to God that they turned out to be all right,” he beamed.
Cikgu Teh, as Sharifuddin was fondly called, said the students who made up the ‘Killerbatch’ group were bright but extremely playful.
“They have since become exceptional citizens,” he said.
