Whilst it is acceptable that topics for component 04 be used in component 06, we do not advise this as best practice. Candidates should have access to a broad and rich curriculum and this approach may well be limiting and possibly self-penalising.
Work completed for component 04 should not be used for component 05. The reason for this is that work completed for component 04 will be under the general guidance of the teacher, but in component 05 support in the preparation of materials (by the teacher) is not allowed. Using component 04 work as part of component 05 could be an example of maladministration of the test.
