Study hard.
Serious project mates and serious polymates. Serious! There were
alot of people in poly during my time that took studies with a play
play attitude, especially in a 26 pt cutoff mechanical engineering
course. Plus, at that impressionable age, it was very easy to think
skipping lectures were cool, acting bo-chap was cool. The Chinese
said, "go in red water become red, go in black water become black".
You are and will be whom you mixed with.
But of course having said that, it doesn;t mean that poly is all
work n no play lah. You have to skip some lectures to call urself a
poly student. Haha!
