Synchronizing prelims and mains preparation is pivotal for UPSC success. Candidates should maintain a dual focus on both phases by regularly revising core subjects and relevant current affairs. Creating an integrated study plan that aligns topics covered in prelims with potential mains questions can enhance efficiency. Utilizing mock tests for prelims while simultaneously preparing for mains ensures overlapping knowledge retention. Building answer-writing skills early, paired with good revision practices, allows smooth transition across phases, maximizing performance in both the preliminary and mains examinations.
