Methodologies to improve critical thinking skills for the UPSC interview include engaging in debates, participating in mock interviews, and analyzing diverse viewpoints. Encouraging learners to question assumptions and explore alternative solutions fosters open-mindedness and independent thinking. Regular practice of case studies enhances the ability to apply theoretical knowledge to real-world scenarios. Structured thinking exercises, such as mind mapping, can clarify thought processes and improve argument formulation. Additionally, creating a habit of reading widely on current affairs promotes informed discussions. Together, these methodologies build a strong foundation for critical analysis and effective communication during interviews.
