To enhance retention of study materials, candidates can employ techniques such as active recall, spaced repetition, and mind mapping. Active recall involves testing oneself on the material rather than passively reviewing notes, which strengthens memory. Spaced repetition helps in revisiting information at increasing intervals, promoting long-term retention. Mind mapping visualizes connections between concepts, making it easier to understand and remember complex topics. Other effective methods include summarizing information in one's own words, teaching concepts to peers, and utilizing mnemonic devices. Regular self-assessment and practice exams also reinforce learning and help identify areas needing improvement.
