UPSC aspirants are allowed a maximum of six attempts to appear for the Civil Services Examination, subject to age limits and category-based relaxations. General category candidates must complete their attempts by age 32, while OBC candidates are allowed a maximum of nine attempts up to age 35. SC/ST candidates receive privileges allowing them unlimited attempts until age 37. It is crucial for aspirants to strategize effectively within these attempts, considering every effort is significant due to the exam's competitive nature. Planning and preparation can maximize their potential during these constrained attempts.
