The maximum age limit for candidates in the UPSC Civil Services Examination is generally set at 32 years, with specific relaxations for candidates belonging to reserved categories. For instance, SC/ST candidates can avail a relaxation of up to 5 years, while OBC candidates receive a 3-year extension. Additionally, candidates with disabilities or those who have prior service in the armed forces may also benefit from extended age limits. Staying informed about these guidelines is essential for planning a timely attempt at the examination.
