Let's not start a quarrel over here on why poly graduates are at an disadvantage in getting into local uni compared to A-level holders. But i hope i can point out some of the reasons why it is so. (These are what I had read from other sources).
Firstly, i must agree with Xinke that it is indeed a small proportion of poly graduates who are able to make it into local uni despite their excellent results.
Many of them who were rejected by local uni went abroad to pursue their degrees and most came back with 1st class honours. So why is it that local uni do not accept them?
Firstly, it was said that Spore is a small economy. The authorities need to "regulate" the number of graduates so that there will not be a situation of over supply of graduates in the local scene. Take a look at countries such as the Philippines, they have so much graduates that most ppl find that their degrees are useless. They could earn much more income by coming to Spore to work as a domestic maid! Yes, the maid u have at home might have a degree back in the Philippines!!!
Secondly, after O-levels, students have 2 choices: to pursue an A-level, which is the DIRECT route to a uni; or to pursue a poly diploma.
We are aware that local education is heavily subsidised by the Gov, where this money comes from taxpayer money. With this in mind, we also know that an A-level education is considered a secondary education while a poly education is a tertiary education.
So the Gov is trying to be fair by allowing students have a fair share of tertiary education. Poly graduates had already enjoyed the benefits of heavy subsidy, while A-level graduates have not. So by fair chance, more places should be made available for A-level students to enjoy the benefit of such heavy subsidy which their peers had already enjoyed while pursuing their diploma.
This is the fair part: Gov do not want some group of the citizens to enjoy "double subsidy" which creates a burden on taxpayers. That is the reason why less positions is available for poly graduates.
Lastly, it rewards those who are willing to take up the challenge to pursue an A-level course after their O-levels. Since we know that the direct route to a uni is tru A-levels, why are some ppl not taking up A-levels in the first place? Because they can't make it into JC based on their best 6 subjects? Because they wanted to avoid GP (General Paper)? Or because they do not want to wear school uniform?
Sorry, i am not trying to create an argument here, but these are the most "popular" reasons why ppl rather take up poly course than A-levels. So to be fair, A-level students should be rewarded with higher chances of getting into local uni although they might not have better capabilities than their peers holding a diploma.
Hope this should solve some of the mysteries in your mind~!
