They often struggle with time management and may feel overwhelmed by the vast amount of information to cover. Understanding the examination pattern, including both the Prelims and Mains, can be daunting for newcomers. Moreover, the pressure to perform and achieve a high rank can lead to anxiety. First-timers should seek guidance from mentors or join coaching classes to navigate these challenges effectively.
