UPSC exam centers are distributed strategically across India to ensure accessibility for candidates. The selection of centers takes into account factors such as population density, regional representation, and logistical feasibility. Major cities like Delhi, Mumbai, and Bengaluru typically host multiple centers due to their high aspirant numbers. The distribution also allows candidates from remote areas to participate, promoting inclusivity. This systemic allocation aims to facilitate a smooth examination experience while accommodating the diverse population of potential candidates.
