GATE 2025 Life Sciences (XL) Detailed Syllabus PDF Download
Overview
The Graduate Aptitude Test in Engineering 2025 is an entrance exam for students aspiring to become postgraduate students in various engineering and science courses such as Life Sciences (XL). It is conducted by IIT Roorkee. It tests not just the candidate's understanding of concepts, but also their ability to translate that knowledge into practice. The scope of the Life Sciences syllabus ranges from biochemistry and microbiology to botany and zoology; the very broad spectrum of these topics ensures a significant comprehensive evaluation of any candidate's understanding. According to a structured format of General Aptitude along with major subjects, GATE ensures a doorway to advanced studies and higher research opportunities in elite institutions. It is, therefore, essential to get familiar with the detailed syllabus so that proper preparation is devised that can strategize study plans and get the most out of performance on the actual day of the exams.
GATE 2025 Exam Pattern
Knowing the exam pattern is important for proper preparation. Here is an elaborated examination pattern of GATE 2025 GATE Physics (PH).
1. Type of Exam

2. Number of Sections
The GATE 2025 Life Sciences exam comprises the following number of sections:
- General Aptitude (GA): This portion tests your fundamental verbal and numerical skills.
- Subject Specific Part: These consist of basic concepts in GATE Life Sciences
3. Type of Questions
MCQs
- For each MCQ, there are four options out of which only one is correct.
- There is a negative marking for wrong answers. Generally, if the question carries one mark, then the penalty would be 1/3 of the mark. For two-mark questions, there will be a penalty of two-thirds of the marks of the question for an incorrect response.
NAT
These are those questions that will carry a numerical type of answer to be filled on the computer screen.
- No negative marking for wrong attempts in the NAT questions
4. Marking Scheme
MCQs:
- Correct answer: Usually 1 or 2 marks
- Incorrect answer: Deduction for wrong answer. For a mark question, 1/3 mark is deducted; for a 2-mark question, 2/3 mark is deducted
NAT:
- No negative marking.
- The full mark is awarded to the right answer to the question.
5. Number of Questions
- Total Questions: GATE consists of a total of 65 questions.
- General Aptitude (GA): A total of 10 questions, out of which 5 will be of 1 mark each and the rest 5 will be of 2 marks each.
- Subject Specific Section: All remaining questions would be on core subjects- GATE Life Sciences and all types of questions are MCQs and NAT.
6. Sections and Weightage
- General Aptitude (GA): This section accounts for nearly 15% of the total marks.
- Subject Specific Section: Subject-specific questions account for the rest of the 85% marks.
