For this 'problems and solutions' essay, your introduction must clearly state your position on the severity of the problems caused by expensive university education and the necessity of implementing effective solutions. While you can briefly acknowledge the inherent value of tertiary education, your core argument should consistently focus on how escalating costs create significant barriers and disadvantages, maintaining this stance throughout your body paragraphs.

When discussing problems, consider the exacerbation of student loan burdens, particularly evident in countries like the USA and UK, leading to delayed life milestones and economic instability. For solutions, you could reference models such as government-subsidized education in Nordic countries (e.g., Finland, Norway) or income-contingent loan schemes like Australia's HECS system, which ties repayments to future earnings.

A common mistake on this question is merely describing the problems and listing generic solutions without deeply analyzing the *causal links* between rising costs and their societal impact, or critically evaluating the *feasibility and efficacy* of proposed remedies. Avoid simply stating 'education is expensive' and 'make it cheaper'; instead, explore the specific mechanisms through which high costs create problems (e.g., reduced access, skill gaps) and how solutions directly address these mechanisms.

Employ a clear cause-and-effect linking strategy to connect problems to their origins and solutions to their intended outcomes. Phrases like 'consequently, this leads to...', 'as a direct result of...', 'this exacerbates the issue of...' are effective for problems. For solutions, use 'to mitigate this challenge...', 'a viable remedy involves...', 'furthermore, addressing this necessitates...' to guide the reader through your arguments logically.

Examiners awarding band 8-9 for this question look for a sophisticated analysis that goes beyond surface-level observations, demonstrating a nuanced understanding of the socio-economic implications of expensive education. This includes exploring interconnected problems (e.g., equity, brain drain, skill shortages) and proposing well-reasoned, specific solutions that consider various stakeholders and potential challenges, all while maintaining excellent grammatical control and a wide range of academic vocabulary.
