A "test" is a method used to assess knowledge, skills, or performance in a specific area. Tests can take various forms, including written exams, practical demonstrations, or oral assessments. They are commonly used in educational settings to evaluate students' understanding of subjects like mathematics or science. In addition to education, tests are also utilized in fields such as medicine to diagnose conditions or in software development to ensure programs function correctly. The results of a test can help identify strengths and weaknesses, guiding further learning or improvement efforts.
