The UPSC Civil Services Exam in India is known for its difficulty, competition, and extensive preparation required. With only a limited number of vacancies available, the competition is high. To stay calm during the exam, it is important to prepare well in advance, maintain a positive perspective, prioritize sleep, and avoid last-minute cramming. During the exam, it is advised to read carefully, seek clarification if needed, move on if stuck, relax when anxious, stay present, and annotate the question paper.
