Cambridge International A-Levels let a student build their own qualification from more than 55 individual subjects rather than follow one fixed national bundle, sitting exams in a May/June or October/November series through a registered school in over 150 countries. Each subject is graded independently on its own A* to E scale across two to four separately weighted papers, with AS-level content often bankable in year one and carried into the full A-Level in year two. Results carry no expiry date from Cambridge and are recognised by more than 2,670 universities across 99 countries, though the actual grades a university asks for are set course by course rather than through one universal Cambridge-wide standard. Its real distinguishing trait against nationally administered variants like Singapore's is the absence of any mandatory General Paper, Project Work, or H1/H2/H3 tiering — every subject here is simply taken and graded as a standalone A-Level or AS-Level.
