A structured approach ensures comprehensive coverage of the vast syllabus while allowing for periodic assessments of progress. It provides clarity on daily, weekly, and monthly goals, reducing uncertainty and anxiety. Moreover, consistent adherence to the plan promotes discipline, enabling aspirants to balance multiple subjects and revision effectively. Staying flexible to adapt the plan as needed is equally important to address specific areas of concern.
