TNUSRB SI source verification

A transparent record of original-paper gaps for the 2010, 2015 and 2020 Sub-Inspector Open / General Candidates papers. Questions and grading are not certified merely because a secondary PDF repeats their text or a final answer-key letter exists.

Not an answer key: “Provisionally scored” means mapped to a published answer table that still needs source review. “Unverified”, “ungraded”, and “blocked” items do not yield correct-answer marks. This tracker excludes all Departmental examination papers.

Missing original source material

2015 Open · production graph

Six questions have an ungraded comparison tracing; the original TNUSRB booklet graph still requires verification.

Playable · comparison only · ungraded

2015 Open Candidates quiz

2020 Series C · recovered source text

Q114–116 have been recovered from a public Series C scan. The source file will be checked on load.

Absent · not playable

2020 Series C General Candidates quiz · Compare Series A/B/C/D final-key positions

Other source checks still pending

2015 Q100: competing secondary copies disagree over option C: 1996 versus 1995. A nonofficial graph from the Athiyaman 2015 compilation is available, but the original TNUSRB booklet graph remains unverified. Do not infer exact data from keys.
2020 Q84, Q95 and Q103: on-site figures are labelled comparison-study redrawings, not certified original Series C diagrams; all remain ungraded.
2020 A/B/C/D booklet series: the final key covers all four position-specific columns, but equal question numbers are not equivalent across series. Inspect the complete matrix and eight documented C↔D question-position matches. C Q114–116 were recovered from the Series C scan itself, not copied by matching numbers from another series.
2020 Q47: matrix options are a Series D comparison, not a verified Series C option layout; ungraded.
2010 Type A Q64: secondary answer-key disagreement. Readable for practice but ungraded until original source and key comparison.

Primary paper and secondary source leads

TNUSRB 2019 recruitment / 2020 examination General Candidates question paper · official-hosted booklet; page images not independently checked (source fetch returned 502 on 12 November 2026).
TNUSRB question paper archive · official directory; not itself proof of every transcription.
2015 Open original-numbered coaching copy · secondary text for Q99–104; it does not establish the missing graph.
2015 Athiyaman subject-grouped PDF, page 25 · contains a 1990–1995 P/Q graph for their Q84–89 corresponding to numbered Open Q99–104. Diagram on ClearExams is an approximate editorial tracing; original official booklet graph remains uncertified.
2015 We Shine Academy copy · secondary PDF indexed with Q100 option C as 1995; no primary-paper visual proof.

To close a gap, the original Open / General Candidates booklet page must visibly establish the full numbered question, all options, and any required graph or figure. Check the matching final key separately and preserve source differences in the audit.

How this tracker verifies claims

Counts below are computed directly from the three published quiz JSON banks. It never estimates a missing chart from multiple-choice options or treats a different booklet series as an exact replacement.
