Children shattered and parents protest

The recent PSLE seemed to be taking its toll on the children if a letter writer is to be believed. Guo Weifu complained that his son was in the top class but came back shattered after the PSLE maths exam. He checked and found that many children also suffered the same fate. The questions were too tough and many were not able to complete half or more of the questions. This is indeed frightening when anything less than 100 marks is deemed no good. And the confidence of the children were literally smashed. Poor children. Poor parents. What is happening huh?
