Strategies to help candidates consolidate their learning for better retention in UPSC preparation include regular revision, active recall techniques, and spaced repetition. Breaking study sessions into manageable chunks allows for more focused learning and prevents burnout. Creating summaries, mind maps, and flashcards helps reinforce key concepts and facilitate self-testing. Group discussions with peers can encourage deeper understanding and retention through collective analysis. Additionally, practicing past exam papers and mock tests enables candidates to identify weak areas and ensure comprehensive coverage of the syllabus. Consistent application of these strategies enhances the likelihood of retaining important information for the examination.
