Candidates should regularly assess their ideas and arguments to identify gaps and areas for improvement. Writing drafts and subsequently reviewing them allows for a better understanding of thesis coherence and argument strength. Engaging with tutors or peer feedback can provide fresh perspectives, prompting necessary revisions. Furthermore, encouraging critical questions about the implications and motivations behind issues discussed in their essays paves the way for more rigorous arguments. Ultimately, this reflective practice results in comprehensive and impactful essays.
