These exams often play a crucial role in determining students' eligibility for higher education or vocational training. They can cover subjects like mathematics, science, and language arts, ensuring a consistent measure of academic achievement across different regions. In many countries, national exams are taken at key stages, such as at the end of high school or middle school. The results can influence students' future opportunities, including college admissions and scholarship eligibility, making them an important milestone in the educational journey.
