1. How marking schemes work
Most quality questions are marked against a banded scheme, for example 0 to 4 or 0 to 5, with a published description of what each score means. A top-band answer is usually described as one that fully addresses the requirement with substantial, relevant, specific evidence. A middle-band answer addresses the requirement but with limited evidence or specificity. Your job is to write, deliberately, to the top-band description.
