Candidates from diverse educational backgrounds face challenges in UPSC due to varying familiarity with curriculum and pedagogical approaches. Those from specialized fields may struggle with general studies subjects, while others may find it hard to adapt to analytical writing. Limited exposure to current affairs or critical thinking can create gaps in knowledge. Additionally, diverse backgrounds may lead to differing study styles, which may not be conducive for the rigorous demands of UPSC. Overcoming these challenges requires dedicated planning and resourcefulness.
