* Primary (ages 5-11): These are younger learners taking exams like Checkpoint.
* Secondary (ages 11-16): This is a large segment, covering GCSEs (IGCSEs internationally) and O Levels.
* Pre-University (ages 16-19): This includes A Levels and AS Levels, preparing students for university.
Therefore, there's no single age group; it depends on the particular exam and the student's academic level.
