Flashcards are simple learning tools that help people memorize information. They usually consist of a card with a question or term on one side and the answer or definition on the other. Students often use flashcards to study for tests, making it easier to remember facts, vocabulary, or concepts. They can be made from paper or created digitally using apps. Using flashcards can make studying more interactive and engaging. By testing themselves repeatedly, learners reinforce their memory and improve recall. This method is popular among students of all ages, from those learning a new language to professionals preparing for certifications like the GRE or MCAT.
