Methods that improve recall of laws and regulations for UPSC exams include using mnemonics, creating flashcards, and engaging in active recall techniques. Incorporating visual aids like charts and mind maps can help in organizing complex information into easily digestible formats. Group study sessions can enhance recall through discussions and quizzes, encouraging candidates to articulate and explain concepts. Regular revision schedules and spaced repetition techniques ensure that information is consolidated effectively over time. Lastly, practical application of laws through case studies helps contextualize content, further reinforcing memory retention.
