For candidates in the general category appearing for the UPSC exam, the age limit is typically set at 32 years, with a relaxation of up to 5 years for candidates from the SC/ST categories and 3 years for OBC candidates. Age limits are crucial since they dictate the number of attempts an individual can make. It is important to refer to the official notifications released by UPSC for the most accurate and updated information regarding age criteria and adjustments due to specific circumstances, such as COVID-19.
