That's not exactly the right way to put it. Wherever you end up it won't be a dead end. No one actually hits one unless they're completely incapable of completing simple tasks. Our society has allowed for it that as long as someone is physically healthy, there will always be a job available. If you had to put it in what you have just said, it'd just be executing a slight prejudice on people based on the form of education they have. As much as this is important, I sincerely doubt it's any cause for grieving over where an individual ends up in.In JC, I think you're pretty much screwed if you don't have a single A grade in your A' Level certificate.
In Poly, you can't go to any local university if the first digit of your GPA is 2.
If you came from ITE, it's pretty much game over.
Having said that, is it not reason enough to work hard? Just do it dammit.
