First-time UPSC aspirants should adopt study methodologies like creating a comprehensive study plan, prioritizing core subjects, and breaking down syllabus into manageable portions. Utilizing NCERT books for foundational concepts, followed by advanced resources for in-depth understanding, is advisable. Regular revisions to strengthen memory retention and targeted practice through mock tests to assess progress are beneficial strategies. Additionally, engaging with peers for group studies can enhance learning and foster motivation, making this journey more effective and less overwhelming.
