CAIE’s linear system requires students to take the exam in two phases
– AS level and A2 level – to make up a full A-Level pass. Each level
accounts for 50% of the total mark. Students dissatisfied with any unit
must re-sit the entire level. Only the last score will be taken for A2
into account. Although universities often require a number of full
A-Level passes for admission, AS grades also attract UCAS points and
are counted for university entrance.
