When preparing the UPSC exam schedule each year, various factors are considered, including the academic calendar, availability of resources, and logistical arrangements for conducting exams across the nation. The schedule must align with the schedule for other competitive exams to avoid confusion among aspirants. Additionally, stakeholders' feedback, including previous candidates, helps in optimizing the exam calendar. The timing for Prelims, Mains, and Interviews is crucial to ensure a smooth process that allows candidates ample time for preparation and minimizes overlaps with other obligations.
