To retain information better for UPSC exam preparation, aspirants should employ techniques like active recall and spaced repetition. Engaging with material through summarization and self-testing reinforces memory. Creating associations with the content through storytelling or mnemonics can facilitate easier recall. Regular reviews at spaced intervals prevent forgetting and strengthen long-term memory. Additionally, integrating different learning styles—visual, auditory, and kinesthetic—can cater to individual preferences and make material more engaging. Lastly, maintaining a positive mindset and using relaxation techniques can minimize stress, aiding concentration and retention during study sessions.
