N1 2011-12 — audit report

70 questions (問題1–13, the non-listening half). Generated from the OCR and correction audit trails.

OCR confidence

Source: mixed — quality 3/5: Cleanly rendered retypeset Word-to-PDF text, fully legible with no scan noise — but the retype has a high typo density, roughly 3-8 errors per question page: kana confusions (あつ for たつ, ぞんな for そんな, にわ/でわ for には/では, だれる for される, ごる for ころ, もちった for もらった), katakana garbles (カワンクー for カウンター, アモン.デユール[]の『ウルフ.シデイ』ハ), dropped characters (ようや for ようやく), stray characters (け before an option), wrong 問題4 header text, and ☆ substituted for the official ★ in 問題6. These are dangerous for a readings/vocab test where exact kana matters, so OCR output needs cross-checking against official sources. The two answer-key pages are low-resolution scanned tables with a 佳禾网校 watermark and Word artifacts, but every cell is readable. Mixed full-width/half-width digits in question numbering throughout.

Every section was transcribed twice independently (a full-page pass and a double-resolution half-page pass) and reconciled. Of 13 sections, 4 agreed on all content between the two passes (reconciled automatically, differing only in transcriber notes) and 9 had at least one content difference resolved by a third adjudication pass that re-read the page images. 157 leaf-level differences were examined in total.
