Proven techniques for effective memorization in UPSC studies include the use of mnemonic devices, active recall, and spaced repetition. Mnemonics help in encoding complex information into more manageable formats, enhancing retention. Active recall involves testing oneself on the material rather than just passive review, which significantly strengthens memory. Spaced repetition, where information is reviewed at increasing intervals, optimizes long-term retention. Moreover, visualization techniques and mind mapping can aid in organizing information, making it easier to recall during exams, ultimately boosting confidence and performance.
