Aspirants can improve their memory retention during UPSC studies through various strategies such as the method of loci, regular revisions, and mnemonic devices. Active learning techniques, like summarizing content in their own words or teaching concepts to others, can enhance understanding. Incorporating visual aids, such as diagrams or mind maps, further aids memory. Additionally, spaced repetition—reviewing material at intervals—helps reinforce knowledge retention over time. Establishing a consistent study routine with breaks also supports improved focus and retention.
