GAT-B Exam : Complete Guide for Biotechnology & Life Science Students
If you are a Biotechnology, Life Science, or related science student and planning to pursue M.Sc., Integrated PhD, or research-oriented higher education, then GAT-B (Graduate Aptitude Test – Biotechnology) is one of the most important exams you should know about.
In this blog, you will get complete information about the GAT-B exam including eligibility, syllabus, exam pattern, why students give this exam, and career benefits after qualifying.
What is GAT-B Exam?
GAT-B (Graduate Aptitude Test – Biotechnology) is a national-level entrance examination conducted for admission into postgraduate and research programs in Biotechnology and allied life science fields.
Earlier known as DBT-BET, the exam is now conducted as GAT-B by NTA (National Testing Agency) on behalf of the Department of Biotechnology (DBT), Government of India.
This exam mainly focuses on testing a student’s conceptual understanding of biology, biotechnology, and related subjects.
Why is GAT-B Exam Important?
Students give the GAT-B exam because:
- ✅ Admission to top DBT-supported institutions
- ✅ Entry into M.Sc. Biotechnology
- ✅ Gateway to Integrated PhD & research programs
- ✅ Strong foundation for research careers
- ✅ Advantage for government & scientific jobs
- ✅ Good option for students not opting for medical entrance exams
If you are serious about a career in research, biotech industry, academia, or government labs, GAT-B is highly beneficial.
