For strategic revision before the UPSC exam, candidates should consider several crucial steps. First, create a revision schedule that prioritizes key subjects and topics, ensuring a balanced focus across the syllabus. Utilize mind maps and summary notes for quick reviews, allowing efficient retention of information. Regularly practice past papers or mock tests to familiarize with the exam format and identify weak areas. Make adjustments to the revision plan based on performance in these tests. Lastly, ensure that time is allocated for self-reflection and relaxation to combat stress and maintain motivation before the exam.
