Candidates can enhance focus during preparation using mental exercises such as mindfulness meditation and visualization techniques. Mindfulness helps in reducing anxiety and enhancing concentration, allowing candidates to focus better on the vast syllabus. Visualization exercises can aid retention by creating mental images of what they study, helping them recall information more effectively during exams. Additionally, techniques like the Pomodoro Technique can improve focus by breaking study sessions into manageable intervals, thereby reducing fatigue. Regular physical exercise also enhances cognitive function, promoting better focus on the overall preparation process.
