For this question, you must state a clear position in your introduction, likely disagreeing with the idea that parents and teachers should *only* focus on performance. While acknowledging the importance of academic achievement, immediately pivot to argue that neglecting emotional well-being is short-sighted and ultimately counterproductive to true success.

To support your disagreement, consider arguments such as the necessity of holistic development for long-term success and well-being, the link between emotional health and sustained academic motivation, and the potential for severe mental health issues (e.g., anxiety, burnout) in high-pressure environments. You could reference educational systems like Finland's, which prioritize play and well-being, yet consistently rank high globally, or contrast this with the rising rates of student depression in highly competitive academic cultures.

The most common mistake students make on this question is failing to address the absolute qualifier 'only focus on' and instead discussing general pros and cons of academic pressure. Avoid sitting on the fence; the prompt's extreme stance ('only focus on performance, not on emotional well-being') demands a strong disagreement, arguing that such an approach is fundamentally flawed and unsustainable.

When structuring your arguments, use a 'concession and rebuttal' strategy. Start a paragraph by acknowledging the opposing view's merit (e.g., 'It is undeniable that academic achievement is crucial for future opportunities...'), then immediately introduce your counter-argument using phrases like 'However, this perspective overlooks the fundamental role of emotional resilience...' or 'Nevertheless, an exclusive focus on grades can inadvertently undermine...'.

Examiners look for a nuanced understanding of the complex interplay between academic pressure and child development for a band 8-9. This means demonstrating how emotional well-being is not merely a 'soft skill' but a foundational component for sustained academic performance, critical thinking, and overall life success. Use sophisticated vocabulary related to child psychology, educational philosophy, and long-term societal impacts, maintaining a consistent, well-supported argument throughout.
