To improve retention of important events in UPSC studies, candidates can employ methods such as the Pomodoro technique, which breaks study time into focused intervals, enhancing memory recall. Utilizing mind maps helps in visualizing connections between events and themes. Regular revision through spaced repetition solidifies learning in long-term memory. Additionally, integrating current affairs journals and summarizing events in a daily planner can aid in contextualizing information. Keeping notes concise yet comprehensive will foster better understanding and retention over time, ensuring that aspirants are well-prepared for the exam.
