British A-Levels are advanced qualifications typically taken by students in the United Kingdom at the age of 16 to 18. They are usually studied over two years and are essential for university admission. Students select a few subjects to focus on, allowing for specialization in areas of interest. The A-Level curriculum includes a wide range of subjects, from sciences like Biology and Chemistry to humanities such as History and English Literature. Assessment is primarily through exams, with some subjects also including coursework. Achieving good A-Level results is crucial for students aiming to pursue higher education.
