+
+| subject | reason |
+|---|---|
+| JC Italian | 23% answer-link; sub-part mis-alignment |
+| LC Accounting | 0% link — scheme is a worked ledger/figures worksheet |
+| LC Economics | 60% link — answers unreliable |
+| LC Home Economics S&S | 47% link |
+| LC Politics & Society | 49% link |
+| LC Classical Studies | 0% link — 'Topic N' essay structure |
+| LC Religious Education | 38% link |
