Candidates can apply problem-solving techniques during Mains exam preparation by breaking down complex topics into manageable parts. Utilizing SWOT analysis (Strengths, Weaknesses, Opportunities, Threats) helps identify areas for focus and improvement. Practicing case studies enhances analytical skills, while regular mock tests foster a structured approach to tackling questions under time constraints. Moreover, employing techniques such as mind mapping can aid in visualizing connections between theories and real-world applications, ensuring a comprehensive understanding of subjects and boosting overall performance.
