These methods help in organizing information visually, making it easier to recall during exams. Techniques such as imagining concepts in a spatial format or associating them with images can also improve understanding and memory recall. Moreover, incorporating visual aids in notes fosters a more interactive learning experience. Regular practice of these techniques cements knowledge and supports long-term retention, vital for the vast UPSC syllabus.
