Test Series 2026 — Recalibration & Hierarchy Spec

Status: awaiting decision on 3 open questions (see bottom) Established: 2026-09-30 Authority: Syllabus/NRE Syllabus 2024.pdf / .docx (PM&DC official) Target app: Test Series/html/NRE Test Series 2026 — by Subject.html Live: https://nre2026.netlify.app/

1. Goal

1000 unique MCQs = 5 full NRE mocks of 200, in one bank, structured so a candidate can drill a single topic without sitting 200 questions.

Distribution must follow the official Table of Specifications weightage.

2. Hard rules

  1. Every MCQ unique. No repeated stem, no repeated concept, no shared option set. Uniqueness is machine-verified, not asserted.
  2. Every MCQ keeps the full 7-layer breakdown: concept, cognitive task, discriminator, why correct, trap type, future alert, why each distractor dies.
  3. NRE style: higher-cognition MCQs, applied not recall, one best answer, no negative marking context.
  4. Subdivision so any leaf topic is independently practisable.

3. Current state — audit of the existing 899

Machine audit run 2026-09-30:

Check Result
Exact duplicate stems 0
Duplicate question IDs 0
Near-duplicate stems (Jaccard >= 0.75) 0
Identical 4-option sets 1 pair
Missing/empty 7-layer fields 0 (all 899 complete)

The one concept-level duplicate:

  • SUR-URO-06 and NW-UR-01 — both “painless haematuria + palpable renal mass -> renal cell carcinoma”. Must be resolved (re-file or re-author one).

The existing 899 are essentially clean. Do not assume they need repair.

4. Official weightage (per 200 MCQs) and the x5 target

Discipline Per 200 Target in 1000 Currently have Delta
Medicine and Allied 52 260 399 -139
Surgery and Allied 48 240 0 +240
Obstetrics & Gynaecology 14 70 80 -10
Paediatrics 14 70 90 -20
Ophthalmology (Eye) 6 30 20 +10
Otorhinolaryngology (ENT) 6 30 40 -10
Applied Anatomy 11 55 40 +15
Applied Pathology 11 55 20 +35
Applied Physiology 10 50 10 +40
Clinical Pharmacology 8 40 10 +30
Applied Biochemistry 6 30 40 -10
Community Medicine 6 30 40 -10
Forensic Medicine & Toxicology 4 20 30 -10
Microbiology (no official discipline) — — 30 -30
Total 196 980 899 +81

4a. The official syllabus does not add up

Basic science rows: 11 + 11 + 10 + 8 + 6 + 6 + 4 = 56 The table header declares “Total 60”. Clinical rows sum to exactly 140.

So 56 + 140 = 196 against a 200-MCQ exam — 4 MCQs are unallocated in the official document. Scaled x5 that is 980 allocated of 1000, leaving 20 unallocated. “Match official weightage exactly” is therefore not fully well-defined. Decision required.

5. The 101 vs 370 conflict

User instruction was “101 more MCQs” and “match the original weightage”. These are mathematically incompatible:

  • Keep all 899 + add 101 = 1000, but Medicine and Allied lands at ~500/1000 = 50% of the bank against an official 26%.
  • Hitting official weightage requires ~370 authored and ~239 retired or re-filed, net +131.

Decision required. See Q1.

6. New hierarchy (user-specified)

Main sections:

  1. Surgery and Allied
  2. Medicine and Allied
  3. Paediatrics
  4. Obstetrics & Gynaecology
  5. Basic Sciences (Anatomy, Physiology, Pathology, Biochemistry, Pharmacology, Community Medicine, Forensic)
    • plus Ophthalmology and ENT as their own sections

Each main section subdivides per the official detailed TOS. Medicine divides into organ systems; Paediatrics and Surgery get the same treatment.

Detailed per-discipline topic lists extracted to Test Series/NRE-2024-Detailed-TOS.txt (17 surgery topics, 16 medicine topics, 11 paediatrics topics, 11 O&G topics, etc.).

7. Reusable material

7a. QBank/ — OFF LIMITS

Per user instruction, QBank/Surgery_MCQs_AnswerKey.docx is not a source and must not be read into, referenced by, or interfered with. All Surgery content is authored fresh. QBank/ is a Protected Area under AGENTS.md anyway.

7b. Test Series/Gap Writers/ — 425 questions

Different content from the app but colliding IDs (e.g. Gap Writers CV-GP-01 is a specific inferior-STEMI/fibrinolysis item; the app’s CV-GP-01 is a generic reperfusion item). Richer metadata than the app: errorLogRecord, distractorExplanations, syllabusTopic, reviseTopic. Files: biochemistry 5, cvs-cardio 40, dermatology 50, grand-set 200, microbiology 30, msk 20, obgyn 10, paediatrics 20, respiratory 50. None of it covers Surgery. Requires a full dedup pass — IDs must be re-namespaced before merging.

8. Non-negotiable guardrails

  • Do not re-file an endocrine/GI question into Surgery just to hit a count. The 22 “surgery-keyword” hits in the existing bank are incidental (thyroidectomy in endocrine stems, hernia in GI stems).
  • Never retire a question without recording its ID in a retirement log.
  • Re-run the uniqueness audit after every batch.
  • The 1.6 MB DATA=JSON.parse(...) payload must be preserved byte-intact through every rebuild, and the file re-verified against this spec’s counts.
