This mock focuses on signature forensics and Indian documentary law: the four recognised forgery types (simulated, traced, freehand, and lifted), electronic signature forgery under BNS 2023 Section 336, the tracing indicators examined on the VSC-8000, and the admissibility framework under BSA 2023 Section 39. Questions test the precise one-parameter distinctions between simulated (model in view) and freehand (no model) forgery, between IPC 463 / BNS 336 (basic forgery), IPC 467 / BNS 338 (will and valuable security), and IPC 471 / BNS 340 (using a known-forged document), and between the five categories of expert opinion under IEA 45 / BSA 39. The Indian case-law anchor is State of UP v Ram Babu Mishra (1980) 2 SCC 343 and Murari Lal v State of Madhya Pradesh (1980) 1 SCC 704, both Supreme Court rulings that established the standard for evaluating questioned-document expert opinion: relevant but not conclusive, requiring independent judicial assessment. The VSC-8000 examination of stroke sequence at ink-line crossings -- using UV fluorescence quenching and infrared luminescence to differentiate inks -- is covered in the final block. CFSL Kolkata's Questioned Documents Division and the Central Document Examination Laboratory (CDEL) are the primary reference institutions for Indian casework of this type. Topics covered: - Simulated, traced, freehand, lifted, and electronic signature forgery - Traced forgery indicators: hesitation marks, uniform line width, absent pen lifts - Signature classification: formal, cursive, initials, and mark types - Genuine intra-writer variation and its range mapping - BNS 336 / IPC 463: forgery definition and intent element - BNS 338 / IPC 467: aggravated forgery of will and valuable security - BNS 340 / IPC 471: using a known-forged document and knowledge element - BSA 39 / IEA 45: expert opinion admissibility and the Ram Babu Mishra and Murari Lal rulings Allow 30 minutes.
This mock covers the forensic science of ink dating and ink examination as tested in UGC-NET Paper II Unit IX (Questioned Documents). Core analytical methods examined include phenoxyethanol (PE) quantification by GC-MS under the Aginsky protocol, thin-layer chromatography (TLC) comparison by the Brunelle method, High-Performance Liquid Chromatography (HPLC) with diode array detection for dye profiling, Laser Desorption Ionisation Mass Spectrometry (LDI-MS) for non-destructive direct-surface ink identification, and Raman spectroscopy for in-situ dye characterisation. The mock also covers ASTM E2789 (Standard Guide for Ink Analysis) and its distinction from ASTM E1789 and ASTM E2390, the US Secret Service Ink Reference Collection (IRC) and its role in establishing earliest-possible writing dates, the logarithmic solvent-loss curve governing PE decay, static versus dynamic (accelerated) aging, sequence-of-strokes examination at ink intersections, and the reliability limitations of the Aginsky method in court testimony. In the Indian forensic context, the mock addresses the questioned document capabilities of CFSL Kolkata and the Government Examiner of Questioned Documents (GEQD) offices including GEQD Shimla. It tests knowledge of how CFSL reports are tendered in Indian courts under Section 293 CrPC 1973 (now Section 336 BNSS 2023) and the practical alternatives used by Indian laboratories when the USSS IRC database is not directly accessible. Questions test both the scientific principles and the procedural and legal framework within which ink examination evidence is used in Indian criminal and civil proceedings. Topics covered: - Phenoxyethanol (PE) composition, decay kinetics, and role as Aginsky age marker - Brunelle TLC method and US Secret Service Ink Reference Collection (IRC) - Aginsky GC-MS protocol: PE/reference ratio, logarithmic decay curve, 1-2 year reliability limit - ASTM E2789, E1789, and E2390: scope distinctions and non-mandatory Guide status - Static vs dynamic (accelerated) aging: kinetic scaling limitations - Sequence-of-strokes examination: oblique-light microscopy and ESDA - LDI-MS: non-destructive direct-surface dye mass fingerprinting - CFSL Kolkata and GEQD Shimla: institutional roles and Indian court tendering Allow 30 minutes.

Questions draw on the legal framework under Bharatiya Nyaya Sanhita (BNS) 2023 Section 178 (formerly IPC 1860 Section 489A-E) for counterfeiting offences and Bharatiya Sakshya Adhiniyam (BSA) 2023 Section 39 (formerly IEA 1872 Section 45) for expert opinion admissibility. This mock is designed for MSc and BSc Forensic Science students, UGC-NET Paper II candidates preparing for Unit IX (Questioned Documents), and investigators and forensic document examiners working on FICN cases. It is also relevant for NFSU entrance examination preparation and for candidates appearing in FACT (Forensic Aptitude and Calibre Test) assessments covering currency examination and forensic law.

This mock tests mastery of the forensic analysis of anonymous and disguised writings, covering linguistic authorship attribution (idiolect, sociolect, register), handwriting disguise methods (slant change, hand change, block-letter adoption, mimicry), indicators of disguise fatigue, habitual features that persist through deliberate concealment (terminal strokes, diacritic placement, spacing rhythm), stylometry fundamentals (function-word frequency profiles, type-token ratio, sentence-length distribution), and computer-assisted forensic stylometry including CUSUM, the Burrows Delta method, and character n-gram models. Landmark cases including the Unabomber manifesto linguistic analysis and the JonBenet Ramsey ransom note are examined alongside the admissibility framework under Section 39 of the Bharatiya Sakshya Adhiniyam (BSA) 2023, which replaces Section 45 of the Indian Evidence Act 1872. Anonymous and disguised writings present a core challenge in Indian forensic practice. The Questioned Documents Division at CFSL Kolkata handles a substantial volume of anonymous threat letters submitted by investigating agencies, and examiners apply both handwriting comparison and linguistic profiling methods to address authorship questions. The graduated CFSL opinion scale (conclusive identification, probable authorship, possible authorship, inconclusive) and the procedural framework under Section 336 of the Bharatiya Nagarik Suraksha Sanhita (BNSS) 2023 governing submission of government scientific expert reports without oral testimony are tested at the application level in this mock. Topics covered: - Anonymous letter analysis: linguistic and handwriting feature integration - Forensic linguistics: idiolect, sociolect, and register as authorship markers - Disguise methods: slant change, hand change, block-letter adoption, mimicry - Indicators of disguise: intra-word slant inconsistency, mixed script style, disguise fatigue - Habitual persisting features: terminal strokes, diacritic placement, spacing rhythm - Stylometry: function-word frequency profiles, TTR limitations, sentence-length distribution - Computer-assisted stylometry: CUSUM, Delta method, character n-gram models - Threat assessment and admissibility: BSA Section 39, BNSS Section 336, CFSL opinion scale Allow 30 minutes.
