After hearing some stories and encounter them personally, advice to that group of people:

Stick your asses in JCs cause you're going to die a very bad shape in tertiary education. I SWEAR! You guys just can't simply work with people in the society if you guys don't learn and stick to your egoistic mentality. You guys are what we call 'damn one kind' in Singlish and the presence of you guys is going to jeopardize the image of the majority that you people are representing. Learn from those experienced one and stop acting as thou you people know everything. Your knowledge is even not at the tip of the pinky compared to the majority. You people decide where you're standing now, so stop complaning and whining as thou you're being forced in this pool full of shit like all the others are. You made that decision yourself and you landed yourself here on where you are.

You people UTTERLY DISGRACED those valuable and experienced one who brought you where you are now.
