**What techniques can improve retention of information for UPSC candidates?**
To improve information retention for UPSC candidates, several techniques can be employed. The use of active recall, such as summarizing information from memory after studying, significantly enhances memory retention. Spaced repetition can also be effective—reviewing concepts at increasing intervals helps embed knowledge over time. Creating visual aids, like charts and diagrams, can make complex information more digestible. Additionally, utilizing mnemonics for memorization and incorporating multiple study methods, including reading, writing, and discussing, can cater to different learning styles. Regular self-assessment through quizzes or flashcards reinforces retention and comprehension.
