The UPSC conducts the Civil Services Examination once a year, which consists of three stages: Preliminary, Mains, and Interview. The Preliminary exam typically occurs in late spring or early summer, followed by the Mains, conducted in the autumn months. This annual schedule allows candidates to prepare thoroughly and integrate their learning across various subjects. While the examination is held annually, some related notifications and updates may occur throughout the year, reflecting ongoing changes and improvements in the process.
