New psle scoring system is more unfair than previous system

Psle results were recently released in singapore. I was looking at the subject marks required for the different levels and it seems that those who score between 45-64 (a 20 mark range) score the same points at 6. I am not sure why we would keep such a big mark range as clearly someone who score 47 vs someone who score 64 would have put different efforts and have different level of knowledge of a subject, Also to get to the best schools in singapore, you pretty much have to score above 90 for everything. It is not often that a person who is a savant in math and science would be equally great at languages or vice versa. #psle #singapore
