GAT-B 2025 Exam Pattern
According to the GAT-B 2025 exam pattern, the question paper contains 160 questions in total, of which candidates must attempt 120. Part A requires answering 60 questions compulsorily, while in Part B candidates must attempt 60 out of 100 questions. The table below summarizes the marking scheme for both sections.
The GAT-B syllabus covers areas such as physics, chemistry, mathematics, biology, basic biology, life sciences, biotechnology and related topics. The syllabus includes the following sub-sections:
Following a disciplined study plan and regular mock tests will boost your accuracy and time management. Prioritize important topics and aim for 4–5 hours of focused study daily. Practising previous year papers helps you understand the type of questions asked in the exam.
Attempt daily GAT-B mock tests to track improvement and refine your time management. Review mistakes carefully and focus on self-study; you may also consult a mentor to correct recurring errors.
The NTA will publish the GAT-B 2025 result on the official website. The merit list will show the ranks assigned to candidates based on their performance. After the exam, candidates can view their results and download rank cards by logging into the official site with their credentials.
Participating institutions will publish waiting lists following the result announcement. Waiting lists are prepared based on candidate ranks and are used by universities during admissions.
