CUET PG 2025 Life Sciences Question Paper with Keys & Explanations PDF Download | helpBIOTECH Academy
helpBIOTECH Academy offers top resources for CUET PG aspirants! The Common University Entrance Test - Postgraduate (CUET PG) 2025 Life Sciences exam (code SCQP17), conducted by NTA, was held between March 13 and 31, 2025. It qualifies candidates for M.Sc. programs in Life Sciences, Biotechnology, Microbiology, Botany, Zoology, and allied fields in central and participating universities. Over 50,000+ students appeared nationwide.
Pattern: 75 MCQs (no separate sections; integrated syllabus), 4 marks each (+4 correct, -1 wrong, 0 unattempted). Total: 300 marks, 120 minutes. Syllabus covers Biochemistry, Botany, Microbiology, Molecular Biology, Zoology, etc., with emphasis on conceptual and application-based questions.
Here's the detailed analysis of topic-wise questions and marks from the actual CUET PG 2025 Life Sciences paper (conducted between March 13-31, 2025). This breakdown covers core units like Techniques & Methods (e.g., microscopy, electrophoresis), Molecular Biology (e.g., replication, repair), and Biochemistry (e.g., proteins, enzymes). High-weightage units include Techniques, Molecular Biology, Genetics, and Microbiology — focus on these for upcoming exams like CUET PG 2026!
CUET PG 2025 Life Sciences - Unit-Wise Question & Marks Distribution (Analysis from PDF & Coaching Reviews)
CUET PG 2025 Life Sciences was moderate overall. Questions tested conceptual depth (e.g., chromatography types, DNA repair) and applications (e.g., blotting, gene cloning). High scorers attempted 60-65 questions accurately for 200+ marks.
