The GCE O-Level, or General Certificate of Education Ordinary Level, is an academic qualification typically taken by students in the United Kingdom and other countries. It is usually completed at the age of 16 and serves as a foundation for further education, such as A-Level courses or vocational training. The O-Level exams assess students' knowledge in various subjects, including mathematics, science, and languages. O-Level qualifications are recognized internationally and are often required for entry into higher education institutions. The exams are graded from A* to E, with A* being the highest grade. Successful completion of O-Levels can enhance a student's opportunities for future academic and career paths.
