Aspirants should revise their study material for UPSC at regular intervals, ideally on a weekly or biweekly basis. This helps to reinforce concepts and transitions learning from short-term to long-term memory, facilitating better retention. Regular revision also unveils weak areas requiring further focus, allowing for timely corrective measures. Practice tests can serve as effective revision tools, simulating examination conditions while reinforcing knowledge. Integrating revision into the study routine ensures that candidates remain familiar with the vast syllabus that UPSC entails, ultimately boosting their confidence.
