To avoid burnout during exhaustive preparation, candidates can adopt several strategies. Firstly, implementing a structured study schedule that includes regular breaks can help in managing mental fatigue. Setting realistic goals and focusing on small, achievable milestones allows for continuous progress without overwhelming oneself. Moreover, incorporating physical activity and relaxation techniques like meditation or breathing exercises can improve mental clarity and reduce stress. Developing a support system through study groups or engaging with mentors provides external motivation and accountability. Lastly, maintaining a balanced diet and ensuring adequate sleep are vital for sustaining high-quality focus and performance.
