Self-discipline immensely affects the success rate of candidates in UPSC examinations. It fosters a strong work ethic, allowing aspirants to adhere strictly to their study schedules and daily targets. With consistent effort, disciplined candidates can cover the vast syllabus more effectively while also balancing revision and practice tests. This structured approach reduces procrastination and enhances retention of information, crucial for the extensive knowledge required for both preliminary and mains papers. Ultimately, self-discipline establishes a routine that prepares candidates for not just the exams, but for the rigorous demands of civil service.
