Primary challenges faced by first-time UPSC aspirants include the overwhelming breadth of the syllabus, managing time efficiently, and coping with exam pressure. Many candidates struggle to find effective study strategies that suit their individual learning styles. The pressure to perform well and the fear of failure can lead to anxiety, negatively impacting preparation. Additionally, first-timers may lack familiarity with the examination format, making navigation during the exam challenging. Establishing a support system and seeking mentorship can help alleviate these challenges and enhance the overall preparation experience.
