Welcome to helpBIOTECH Academy's dedicated page for the GAT-B 2024 exam! The Graduate Aptitude Test - Biotechnology (GAT-B) 2024, conducted by the National Testing Agency (NTA) on behalf of the Department of Biotechnology (DBT), was held on April 20, 2024. This computer-based test (CBT) lasted 3 hours (180 minutes) and aimed to select candidates for M.Sc. Biotechnology and allied programs in participating institutions across India. Over 10,000+ students appeared, with results declared in May 2024.

The exam pattern included two sections: Section A (60 compulsory MCQs at 10+2 level, 1 mark each, covering Physics, Chemistry, Maths, Biology, and General Aptitude) and Section B (100 MCQs at graduate level in Biotechnology, but attempt only 60, 3 marks each). Negative marking: -0.5 for Section A wrong answers, -1 for Section B. Total marks: 240 (60 from A + 180 from B).

Here's the detailed analysis of topic-wise questions and marks from the actual GAT-B 2024 Biotechnology paper (conducted on April 20, 2024). This breakdown covers Section A (10+2 level basics, 1 mark each) and Section B (graduate-level biotech concepts, mostly 3 marks each). High-weightage units include Biochemistry, Molecular Biology, Genetics, Immunology, and Recombinant DNA Technology — focus on these for upcoming exams like GAT-B 2026!

GAT-B 2024 - Unit-Wise Question & Marks Distribution (Based on Memory & Coaching Analysis)

From student feedback and expert reviews, GAT-B 2024 was moderate overall. Section A was easy-moderate (focusing on conceptual basics), while Section B was moderate-difficult (analytical questions in biotech). High scorers targeted core topics like Proteins, Genetics, and rDNA.

Key Insights from GAT-B 2024 Paper:

  • Overall Difficulty: Moderate (Section A: Easy-Moderate; Section B: Moderate-Difficult). Questions tested conceptual understanding and application.
  • High-Weightage in Section B: Molecular Biology and Biochemistry (30-45 marks) — many analytical questions on enzymes, DNA replication, and protein structure.
  • Surprises: More emphasis on rDNA techniques and immunology than previous years; fewer on bioinformatics.
  • Preparation Tip: Master graduate-level biotech syllabus (as per DBT guidelines). Practice previous papers like this 2024 one for time management — aim for 100+ marks for top ranks.
