GAT B Syllabus 2025: Overview

The GAT-B 2025 exam will consist of two sections: Section A and Section B. The question paper will include Multiple Choice Questions (MCQs) with a total duration of 180 minutes (3 hours). Below is a quick overview of the Graduate Aptitude Test Biotechnology 2025 syllabus and exam pattern.

GAT B Exam Pattern 2025

The Graduate Aptitude Test – Biotechnology (GAT-B) 2025 is a national-level entrance exam designed for admission to the DBT-supported Post Graduate (DBT PG) Programme in Biotechnology. The exam is conducted as a Computer-Based Test (CBT) and consists of Multiple Choice Questions (MCQs). The total duration of the exam is 180 minutes (3 hours), and it is divided into two sections: Section A and Section B. In the Graduate Aptitude Test Biotechnology 2025 exam, unattempted questions will neither be awarded nor deducted any marks, ensuring no penalty for leaving questions unanswered.

GAT Biotechnology Syllabus for Section A

Section A of the GAT-B 2025 exam focuses on testing candidates knowledge at the 10+2 level in four core subjects: Physics, Chemistry, Mathematics, and Biology. This section consists of 60 compulsory multiple-choice questions, with each correct answer carrying 1 mark. However, there is a negative marking of 0.5 marks for each incorrect answer.
