For effective long-term retention of UPSC study material, candidates can employ techniques such as spaced repetition, where revision is systematically spaced over increasing intervals of time. Active recall methods, like flashcards or practice questions, can enhance memory retention. Summarizing information in one’s own words and teaching it to others can further cement understanding. Additionally, self-testing helps identify gaps in knowledge, allowing for focused revision. Maintaining organized notes and periodic comprehensive reviews will also contribute to a well-structured retention strategy, essential for handling the expansive syllabus.
