Furthermore I think you're disregarding the fact that not all Accountancy grads from Local Unis have a 100% guaranteed chance of getting in too. Thus able to get in even though you're from SIM means a great deal to some of us.

Of course it's not the ONLY route to success, but it's a decent starting point where many dream about.

Lastly, you can't compare IB to careers in Accountancy. Its akin to comparing apples and oranges. However, again it's not impossible. Go do a quick search on LinkedIn and you can see that there are SIM students who managed to venture into IB. So it's definitely possible. But what they had sacrificed and fought for to achieve that you would have to ask them yourself.
