To understand why these \u201ckiller questions\u201d loom so large, we need to recognise that 12-year-olds are neurologically unfinished. Their prefrontal cortex, which is responsible for decision-making, planning, impulse control and emotional regulation, is still undergoing active construction.<\/span><\/p>\n The far-from-mature brain explains why Primary 6 students would struggle with challenging questions, particularly complex ones that need strategic thinking or high-level problem-solving. Expecting them to demonstrate composure, reasoning and speed under exam stress may be ambitious and unfair.<\/span><\/p>\n Students with certain conditions are particularly vulnerable in high-pressure exam settings. A<\/span>n estimated 5 per cent to 8 per cent of school-age children have attention deficit hyperactivity disorder (ADHD), and 3 per cent to 10 per cent of students have dyslexia.<\/span><\/p>\n Students with ADHD may have difficulties with concentration and time management, and would tend to falter with complex questions under timed conditions. Those with dyslexia, who process language more slowly even when comprehension can be strong, would likewise suffer.<\/span><\/p>\n Children with anxiety tendencies are especially sensitive. When a difficult question triggers their stress response, their working memory can collapse, leaving them momentarily unable to think clearly, even if they know the content.<\/span><\/p>\n This problem is not hypothetical. Research in developmental neuroscience consistently confirms that acute stress impairs executive functions such as working memory, cognitive flexibility and attention \u2013 precisely the skills needed to handle novel problems.<\/span><\/p>\n The killer questions can inadvertently punish students even if they possess exceptional creativity, intelligence or long-term potential.<\/span><\/p>\n In any case, if the child\u2019s difficulty is not in understanding the concepts but in filtering noise and managing anxiety, then killer questions are measuring the wrong construct. It is assessing neurological maturity under stress, not cognitive potential.<\/span><\/p>\n<\/div>\n
