Practice with national-level exam (FACT, FACT Plus, NET, CUET, etc.) mocks, learn from structured notes, and get your doubts solved in one place.
Timed practice tests with instant scoring and per-question explanations.
This mock covers the analytical instruments and laboratory techniques that form the foundation of forensic science practice, aligned with Unit II of the UGC-NET Forensic Science syllabus (Subject Code 82). Every question targets a concept that appears consistently in NET Paper II, from the basic principles of each instrument to its specific forensic application. Thirty questions span the complete Unit II topic list. The microscopy section covers the polarizing microscope and birefringence, the comparison microscope used in ballistics, the stereoscopic microscope for preliminary examination, the fluorescence microscope for trace dye detection, and the scanning electron microscope for surface imaging. The spectroscopy section tests Beer-Lambert's law in UV-Vis, the fingerprint region in IR, the principle of Raman scattering, the hollow cathode lamp in AAS, and the emission basis of AES. Single questions address neutron activation analysis and the distinction between XRD and XRF. The chromatography section covers the Rf value in TLC, stationary phase in GLC, the pump in HPLC, HPTLC improvements over conventional TLC, and real forensic applications of each method. Hyphenated technique questions test the role of the GC in GC-MS, the ICP torch in ICP-MS, when to choose LC-MS over GC-MS, and the isotope ratio principle of IR-MS. Electrophoresis questions address the electric field as driving force, high versus low voltage separation, and immunoelectrophoresis. Immunoassay questions cover ELISA, Western blotting, and lateral flow strip tests. It is designed for MSc forensic science students and NET/JRF aspirants building their first systematic pass through Unit II before attempting medium and hard difficulty mocks. Themes covered: - Microscopy: polarizing, comparison, stereoscopic, fluorescent, and scanning electron microscopes - Spectrophotometry: UV-Vis Beer-Lambert law, IR fingerprint region, Raman scattering, AAS, and AES - X-ray techniques and NAA: XRD phase identification, XRF elemental analysis, neutron activation analysis - Chromatography: TLC Rf value, GLC stationary phase, HPLC pump, HPTLC advantages - Hyphenated techniques: GC-MS separation role, ICP-MS torch function, LC-MS analyte selection, IR-MS provenance - Electrophoresis and immunoassays: driving force, high vs low voltage, ELISA, Western blot, lateral flow Each explanation follows a three-paragraph structure: the correct answer with technical depth, the distractors addressed as prose, and exam relevance with a memory shortcut. Every question cites a standard reference text.
This easy-level mock covers the foundational vocabulary and essential knowledge of forensic science — every key definition, founding figure, date, and core principle that NFSU MSc, FACT, and UGC-NET candidates must know before approaching application-level material. All thirty questions are pitched at the definitional level, making this the ideal starting point for students new to the subject and an effective revision tool for checking foundational knowledge. Questions cover Locard's Exchange Principle (who, when, and its bidirectional investigative implication), the three founding figures most often tested (Orfila for forensic toxicology, Gross for criminalistics, and Landsteiner for the ABO blood group system), the history of the world's first fingerprint bureau (Calcutta 1897, Henry + Haque + Bose), Galton's 1892 statistical proof of fingerprint individuality, the Lyon Laboratory (1910), the Frye general acceptance standard (1923), chain of custody, physical evidence, trace evidence, secondary transfer, the three principal fingerprint pattern types, latent vs patent vs plastic fingerprints, forensic entomology's minimum PMI function, forensic odontology's three applications, forensic geology's soil comparison role, the AFIS candidate-list function, ACE-V, the principle of individuality, direct vs circumstantial evidence, the Innocence Project, the FBI Laboratory (1932), CFSL structure under MHA/BPR&D, and the NFSU Act 2020. Pitched at first-year BSc and MSc Forensic Science students at NFSU, LNJN-NICFS, and affiliated universities; FACT aspirants covering the General Forensic Science paper for the first time; and UGC-NET candidates building their forensic science foundation. Themes covered: - Locard's Exchange Principle: formulation, Lyon 1910, bidirectionality, investigative implication - History: Orfila (1813), Gross (1893), Galton (1892), Calcutta bureau (1897), Landsteiner (1901), FBI Lab (1932) - Evidence: physical, trace, class vs individual, direct vs circumstantial, chain of custody, secondary transfer - Fingerprints: three pattern types, latent vs patent vs plastic, AFIS, ACE-V - Forensic disciplines: entomology (minPMI), odontology, geology - Indian forensic institutions: CFSL under MHA/BPR&D, NFSU Act 2020 - Expert witness: Section 45 IEA / Section 39 BSA Each question carries a detailed explanation citing Saferstein's Criminalistics, James and Nordby's Forensic Science, Lee and Gaensslen's Advances in Fingerprint Technology, and primary Indian legal sources.
