JC/LC Exam-Paper Extracted JSON
Per-question / per-sub-part JSON extracted from the raw Irish State Examinations PDFs in this dataset. One record per sub-part.
Vision tier: 12 subjects, 5,416 records (JC Maths + all diagram-heavy subjects).
JC Maths & diagram-heavy subjects — VISION-extracted (new)
Extracted by a Claude vision pass that reads rendered page images (equations, lab diagrams, experiments, graphs, circuits, technical drawings, design briefs) that no text layer can represent. Same 16-field per-sub-part schema. Marks are conservative: explicit per-part marks are high; grouped/shared scales are split and tagged derived; no usable scheme gives null marks + uncertain. Answers are pulled from real marking schemes — never fabricated. null answers are expected and legitimate where no marking scheme was ever published (Irish-language IV papers and 2026 papers), not a parse failure. Visual Art has no written exam and is represented by per-Element rubric records.

Updated in this revision
Newly recovered/improved subjects (extracted from the on-disk files, which are the source of truth — the generator and JSON have diverged and must not be re-run). Partial subjects are real but below the gold subjects' ~100% link; unlinked records carry a null answer, never placeholder text.
| scope | subject | records | linked | status |
|---|---|---|---|---|
| JC | History (JC) — old-era HL/OL answers re-linked 40%->89% (front-matter de-hijack); new-era unchanged | 896 | 69% | updated |
| JC | Geography (JC) — old-era Section-1 short answers 0%->72%; new-era unchanged | 934 | 75% | updated |
| JC | Italian (JC) — 10%->47% (Q.N scheme headers recovered); partial, below gold parity | 1,234 | 47% | new |
| LC | Accounting (LC) — 0%->53% (bespoke ledger/worked-solution parser); Irish + figures-only schemes still lost | 2,608 | 53% | new |
| LC | Economics (LC) — 58%->67% (section-prefix-agnostic linking); partial | 2,394 | 67% | new |
| LC | Politics & Society (LC) — 47%->70% (section-prefix-agnostic; essay-rubric boilerplate excluded); partial | 642 | 70% | new |

Outstanding / not yet done
- Image/diagram-heavy LC Maths and all Sciences, practical/graphics/tech, and Music (aural) — vision pass (the JC Maths + Sciences + practical/graphics/tech vision pass is DONE — see the vision tier above)
- Geography MAPS (JC + LC) & OS-map/diagram questions — unparsed (vision)
- Old-era (HL/OL) linking tails not yet done: Spanish, Jewish Studies, and the LC old-format tails of Business, Geography, Agricultural Economics
- Leaving Cert Applied (LCA) & LCVP task components — not indexed, not attempted
- Newly-added subjects above are PARTIAL (47–70% / Accounting 53%) — unlinked records carry a null answer (never garbage); not at gold parity
