Exam fatigue can significantly impact performance during UPSC exams. Prolonged study sessions without adequate breaks can lead to mental exhaustion, reducing focus and retention. Candidates may struggle with concentration and decision-making, potentially affecting their ability to recall information. This fatigue can result in negative self-talk and decreased confidence, further hampering performance. Effective time management and practice tests are essential in mitigating exam fatigue. Implementing regular breaks, relaxation techniques, and maintaining a healthy lifestyle can help manage energy levels, ensuring aspirants are better prepared for the exam day.
