State your clear position in the introduction by explicitly outlining the 2-3 main causes you will discuss and the 2-3 most impactful solutions you will propose. While acknowledging that other factors exist, ensure your essay consistently prioritises and defends your chosen primary causes and solutions, using phrases like 'While X contributes, it is Y that serves as the predominant factor.'

For causes, consider specific examples like the pervasive influence of social media platforms (e.g., studies from the Pew Research Center linking screen time to anxiety) or intense academic and economic pressures (e.g., the high-stakes educational systems in East Asian countries). For solutions, you could suggest integrated mental health literacy programs in schools (e.g., models implemented in Australia) or government-subsidised community mental health services.

The most common mistake students make on this question is providing a superficial list of many causes and solutions without developing any in depth. To avoid this, select only 2-3 main causes and 2-3 main solutions, dedicating a full body paragraph to each, providing detailed explanations, specific examples, and logical connections to demonstrate a comprehensive understanding.

Employ a clear linking strategy by using topic sentences that signpost the paragraph's focus and connect back to your overall argument. For instance, transition from causes to solutions with phrases like 'Having explored the primary drivers of this trend, it is imperative to consider viable remedies,' or 'To mitigate these escalating issues, one crucial step involves...'.

For a band 8-9 answer, examiners look for a nuanced understanding of the *interconnectedness* of causes (e.g., how digital pressures exacerbate academic stress) and solutions that are not only practical but also address the *root causes* identified. The essay must demonstrate sophisticated vocabulary related to mental health and societal trends, complex sentence structures, and a consistently clear, well-supported argument throughout.
