A-levels, or Advanced Level qualifications, are a set of exams taken by students in the UK, typically at the age of 16 to 18. They are an important step for students who wish to pursue higher education, as universities often require specific A-level subjects for admission. Students usually choose three or four subjects to study in depth, allowing them to specialize in areas of interest. The A-level curriculum covers a wide range of subjects, including Mathematics, Biology, History, and English Literature. Each subject is assessed through exams and sometimes coursework, with grades ranging from A* to E. Achieving good A-level results can open doors to various career paths and further studies.
