The importance of proofreading cannot be emphasized enough, as it is one of the key factors that distinguish a 6.5 from a 7.0 or a 7.0 from a 7.5/8.0. While these mistakes may seem silly or unrealistic for someone with an apparently good level of English, you’d be surprised how often candidates—even those scoring 8 or 9—make errors under exam pressure. Therefore, it is crucial to allocate 5–10 minutes to check and edit your work. The most common mistakes include subject-verb agreement errors and spelling inaccuracies, which can significantly impact your score if overlooked.

One of the solutions to housing problems is increasing the availability of affordable housing units in urban areas, which not only addresses the immediate issue of shelter but also promotes economic stability in the long term. Governments, along with private developers, play a crucial role in implementing policies that encourage the construction of low-cost homes, particularly in regions where housing demand is significantly higher than supply. While offering subsidies or tax incentives to builders who prioritize affordability helps reduce the financial burden on low-income families, ensuring strict regulations on housing quality is equally important to prevent substandard living conditions.
