I've read and known of ITE grads who have made it good.
It wasn't so long ago that I read in the newspapers about some ITE graduate who got first class honours in a university in Australia. His mother (who works as a hawker) had to make plenty of sacrifices for the sake of her son.
Don't believe the hype about ITE being 'It's The End'.... it's more about how you choose to spend your time in ITE.
If you choose to believe in narrow-minded idiots who believe that 'It's The End', then it really is the end.... but if you want believe that 'It's Time to Excel', then you can really excel.
