Visualization techniques like mind mapping and infographics can significantly aid UPSC candidates in better retention of facts. By associating information with visual elements, candidates can create mental connections that enhance memory. Techniques such as sketchnoting allow for summarizing complex topics visually, making recall easier during exams. Regularly practicing these techniques not only boosts understanding but also enables candidates to interact with material creatively, which can improve overall learning outcomes, particularly in tackling vast subjects within the UPSC syllabus.
