Self-testing is a method where individuals assess their own knowledge or skills on a particular subject. This can involve answering questions, solving problems, or completing tasks without external assistance. It helps reinforce learning and identify areas that need improvement. Many people use self-testing as a study technique, often employing tools like flashcards or practice quizzes. This approach is beneficial because it encourages active recall, which enhances memory retention. Additionally, self-testing can boost confidence by allowing individuals to track their progress over time.
