A Levels Grading System Explained

The grade scale

Cambridge International A Level and Pearson Edexcel International A Level report A* (the highest) to E. A result below E is ungraded. Cambridge AS Level uses lower-case letters, a to e.

How AS and A2 results combine

In a staged course, the marks from AS components and A2 components are combined, each weighted as the syllabus states. Some boards convert component marks to a uniform scale before combining them, so that results are comparable between series.

The A* grade

The A* usually has an extra condition beyond an overall A, linked to performance in the A2 part. The condition differs between boards and can change, so check your syllabus.

Grade thresholds

Thresholds are the marks needed for each grade and are set after each series. They vary between series, so plan to earn secure marks across the paper instead of aiming at one figure.
