Everything You Need to Know - Syllabus, Pattern, Eligibility, Cutoffs, Strategy & Papers
Exam Overview
GAT-B (Graduate Aptitude Test–Biotechnology) is a national-level entrance examination for admission to DBT-supported postgraduate programs in Biotechnology and allied areas across participating universities and institutions in India. It is conducted by the National Testing Agency (NTA) on behalf of the Department of Biotechnology (DBT), Government of India, with the Regional Centre for Biotechnology (RCB), Faridabad serving as the nodal implementation agency.
GAT-B is not just an exam - it is the gateway to an entire ecosystem of DBT-funded postgraduate education. Every student admitted through GAT-B receives a monthly stipend from DBT, making it one of the few M.Sc. entrance exams in India where the government directly funds your postgraduate education.
Key Facts at a Glance
Who Should Take This Exam?
If you are a B.Sc. student wanting to pursue a research-focused postgraduate degree in Biotechnology, Agricultural Biotech, or Computational Biology with complete financial support (monthly stipend), GAT-B is the premier exam. It provides a gateway to JNU, BHU, HCU, PGIMER, and IIT Indore.
GAT-B vs other exams
GAT-B vs IIT JAM BT: JAM gives you IITs. GAT-B gives you ~79 participating universities including JNU, BHU, HCU, PGIMER, and IIT Indore. Different institution pools, significant syllabus overlap in biology. GAT-B vs CUET PG: Both provide access to central universities. However, GAT-B is specifically designed for biotechnology and allied areas and comes with a DBT stipend; CUET PG does not. GAT-B vs GATE XL/BT: GATE leads to M.Tech, PhD, and PSU recruitment. GAT-B leads to M.Sc./M.Tech. in DBT-supported programs with stipend. They serve different purposes and can be pursued in parallel.

GAT-B stands for Graduate Aptitude Test–Biotechnology. It is conducted by the National Testing Agency (NTA) on behalf of the Department of Biotechnology (DBT), Government of India. The Regional Centre for Biotechnology (RCB), Faridabad is the nodal agency.
At most participating universities, admission is purely based on your GAT-B score and rank. There are no additional interviews or written tests. You apply to universities with your GAT-B scorecard, and they admit based on merit.
You attempt 120 questions total - all 60 in Section A (compulsory) and any 60 out of 100 in Section B (your choice). The strategic selection of which 60 to attempt in Section B is the defining feature of this exam.

Yes. All students admitted to DBT supported programs through GAT-B receive a monthly stipend: ₹5,000/month for M.Sc. Biotechnology, ₹7,500/month for M.Sc. Agricultural Biotechnology, and ₹12,000/month for M.Tech. and M.V.Sc. programs.
Strongly recommended. JAM BT (February) happens two months before GAT-B (April), and the biology syllabus overlap is substantial. GAT-B gives you access to ~79 institutions that JAM does not cover, including JNU, BHU, UoH, and PGIMER.
Yes. You can apply to as many participating universities as you want using your GAT-B scorecard. There is no centralized counselling - each university handles its own admissions, so you must apply individually to each.
Biochemistry, Molecular Biology, and Immunology are the three highest-yield subjects - they consistently contribute over half of Section B questions. After these, Cell Biology, Genetics, and Microbiology are strong supporting subjects.
GAT-B is not about easy or hard - it is about strategy. The exam's unique 60-out-of-100 selection format means that a student who knows 60% of the syllabus but selects wisely can outscore a student who knows 80% but selects poorly.
No. The GAT-B score is valid only for the admission cycle of the year in which you appeared. If you do not secure admission in the current cycle, you must reappear the following year.
Yes. Candidates appearing for their final year qualifying examination (result awaited) are eligible. They must submit an Undertaking/Attestation Form certified by the Head of their Institution at the time of application.
