The APS (Admission Point Score) is calculated from a learner's six best matric subjects, always excluding Life Orientation regardless of the mark achieved. Each of those six subjects is converted into points on a 1-7 scale based on the percentage achieved: 80-100% earns 7 points, 70-79% earns 6 points, 60-69% earns 5 points, and so on down to a 1 for the lowest achievement band. Adding the six subject scores together gives a maximum possible APS of 42.
Most South African university programmes require an APS somewhere between 18 and 36, though highly competitive programmes such as Medicine, Actuarial Science, or Engineering at top universities often set additional subject-specific minimums, for example a minimum percentage in Mathematics and Physical Sciences, on top of the overall APS requirement.
