* Past Series Appearance Percentage is correct up to and including exams from June 23 and is specific to AQA.

Where sensible some "skills" have been grouped together to form a "topic". For example "drawing histograms" and "interpreting histograms" group together to give "histograms". In such cases the percentage shown will be the same for both topics and reflect the overall appearance of histograms rather than the separate skills.

Where topics are at grade 5 or below the percentage may differ from higher and foundation tier. In these cases the foundation percentage has been given.

These percentages are designed to give an idea of how frequently topics have appeared on past exams. They are not an indicator of the relative likelyhood that topics will appear on future exams and should be used with caution. The best way to prepare for examinations is to prepare for all topics.
