Regional disparities can affect UPSC aspirants' performance by creating differences in access to quality resources and coaching. Candidates from urban areas often benefit from better educational facilities, experienced mentors, and extensive study materials compared to their rural counterparts. This uneven access can lead to performance gaps in the examination. Furthermore, socio-economic factors and networking opportunities also play pivotal roles in shaping preparation strategies. Addressing these disparities requires targeted interventions and policies to ensure equal opportunities for all aspirants, regardless of their background.
