Effective summarization improves study efficiency for UPSC aspirants by condensing information into manageable, key points that are easier to recall. This practice encourages active engagement with the material, requiring learners to process and synthesize content strategically. Writing summaries promotes deeper understanding and retention compared to passive reading. Furthermore, summarization aids in identifying critical themes and concepts that align with the UPSC syllabus, which is vast and demanding. By focusing on essential information, aspirants can streamline their revision process, making it more productive and less overwhelming when preparing for exams.
