The UPSC civil services examination is typically conducted once a year, with the preliminary exams occurring in the first half of the year, followed by the mains in the latter half. This annual schedule provides candidates with ample opportunity to prepare thoroughly. However, the single annual opportunity requires aspirants to be disciplined and committed, as they must maximize their preparation in the time available. Understanding this annual framework is crucial for effective planning and strategizing to ensure success in the demanding selection process.
