Use the correct paper and marking scheme

Choose the examination year and paper number first. Check the alternative, paper code, practical instructions and question numbering before using an answer file. A combined marking scheme may cover several papers; its filename remains visible so you can confirm which part applies. Dates inferred from a single-year source collection should be checked inside the document.
