A study aid is any tool or resource that can help a student learn and retain information. Common study aids include grants, flashcards, mnemonics, and Nodoz. Grants are financial awards given to students to help pay for educational expenses. Flashcards are cards with questions and answers written on them, used to help memorize facts. Mnemonics are memory techniques that use associations between easy-to-remember words and phrases to help remember facts. Nodoz is a brand of caffeine pills used to help stay awake and alert while studying.
