First-time UPSC exam takers face several unique challenges including intimidation from the vastness of the syllabus, the high competition, and the pressure of the examination format. They often struggle with time management due to the extensive material that needs to be covered. Additionally, the examination pattern can be overwhelming, particularly the need for effective answer writing and managing multiple papers on the exam day. Emotional stress and the fear of failure can also impact their performance, making it crucial to prepare both academically and mentally.
