Self-testing is a method where individuals assess their own knowledge or skills in a specific area. This can involve quizzes, practice exams, or even informal assessments like flashcards. The goal is to identify strengths and weaknesses, helping learners focus on areas that need improvement. This technique is widely used in education and professional development. By regularly engaging in self-testing, individuals can enhance their retention of information and boost their confidence. It is often recommended as a study strategy, as it encourages active recall, which is more effective than passive review methods like reading or highlighting.
