The key components of a holistic approach to UPSC exam preparation include comprehensive subject knowledge, effective time management, consistent practice through mock tests, and a balanced lifestyle. Candidates should develop a focused study plan inclusive of current affairs, revision, and relaxation time. Incorporating varied study methods fosters better retention and understanding, while self-care practices, such as physical exercise and mindfulness, promote mental well-being. Furthermore, seeking peer and mentor support enhances learning, providing diverse insights and feedback necessary for navigating the complexities of the exam effectively.
