Mock exams are practice tests designed to simulate the conditions of real exams. They help students prepare by familiarizing them with the format, types of questions, and time constraints they will face. Taking mock exams can reduce anxiety and improve performance by allowing students to identify their strengths and weaknesses. These practice tests are often used in educational settings, such as schools and universities, to assess a student's readiness for upcoming assessments. Teachers may provide feedback on mock exams, helping students understand where they need to focus their studies before the actual exam day.
