INBO is the second stage of India’s Biology Olympiad programme and is conducted under the national Olympiad programme coordinated by the Homi Bhabha Centre for Science Education (HBCSE).

Students qualify for the Indian National Biology Olympiad 2027 after clearing the prescribed selection process through the National Standard Examination in Biology (NSEB). Candidates preparing for the INBO exam 2027 can check the exam date, eligibility, syllabus, selection process and preparation details below.

INBO 2027 Exam Date and Timings

The INBO 2027 exam will be held on January 31, 2027. The examination will take place from 1:30 PM to 3:30 PM. Students selected through the prescribed NSEB process will be eligible to appear for the second-stage examination.

Candidates should keep checking official notifications for information related to examination centres, admit cards, selection lists and other important instructions.

INBO 2027: What is Indian National Biology Olympiad?

The Indian National Biology Olympiad (INBO) is the second stage of India's Biology Olympiad programme. Students first appear for the National Standard Examination in Biology (NSEB), and candidates who qualify through the prescribed selection criteria advance to INBO.

The INBO exam tests students on their understanding and application of biological concepts rather than only their ability to memorise facts. Questions can involve biological processes, diagrams, data interpretation and different application-based situations.

The broader Biology Olympiad selection process subsequently includes further stages for identifying students who will represent India at the International Biology Olympiad.

INBO 2027 Eligibility

The INBO 2027 eligibility criteria are linked to the NSEB qualification and the rules prescribed for the 2026-27 Science Olympiad programme.

Students must qualify through the prescribed NSEB selection process to become eligible for the Indian National Biology Olympiad 2027. The HBCSE information for the current Olympiad cycle specifies citizenship, age, schooling and Class 12-related conditions for Biology candidates.

Candidates should check the latest official eligibility notification before appearing for the examination because eligibility conditions can change from one Olympiad cycle to another.

INBO 2027 Selection Process

The INBO 2027 selection process begins with the National Standard Examination in Biology. Students who meet the required qualification criteria in NSEB are shortlisted for the second stage.

The selection pathway broadly includes:

1. National Standard Examination in Biology (NSEB)
2. Indian National Biology Olympiad (INBO)
3. Orientation-cum-Selection Camp (OCSC)
4. Pre-Departure Camp (PDC)
5. International Biology Olympiad (IBO)

The Indian National Biology Olympiad is therefore an important stage for students aiming to progress towards India's international Biology Olympiad team.

INBO 2027 Syllabus

The INBO 2027 syllabus broadly covers senior-secondary Biology and requires students to understand concepts and apply them to questions.

Important areas include:

• Diversity of living organisms
• Structural organisation of organisms
• Cell structure and function
• Plant physiology
• Human physiology
• Genetics
• Ecology
• Evolution
• Biodiversity

Students should also develop the ability to interpret biological information and apply basic mathematical concepts wherever required.

For INBO preparation 2027, students should focus on conceptual understanding instead of relying entirely on memorisation.
