INBO Exam - Indian National Biology Olympiad, Eligibility Criteria, Exam Pattern & Syllabus

The goal of the international Olympiad movement is to bring together the world's most talented secondary and upper secondary students in a friendly competition at the highest level. The Olympiads do not directly lead to career benefits; rather, they serve as a catalyst for people to pursue careers in science or mathematics and embark on a lifelong adventure into the regions of interesting intellectual difficulties. The Olympiads are more than just competitions; they are gathering grounds for the world's greatest young minds, and many connections formed during the Olympiads become the seeds of subsequent scientific collaboration. The Olympiads, like the Olympics in sports, are a celebration of the best in high school science and mathematics.

INBO Eligibility Criteria

Indian Olympiad Qualifier in Biology(IOQB): 16 January 2022 (Sunday), 14:30–18:00 hrs

The national Olympiad programme in science subjects will now be split into two stages, with the international Olympiads taking place in 2021, rather than three.

• The Indian Olympiad Qualifier (IOQ) will be the first stage in 2020-2021.

• The next phase will be the Orientation and Selection Camp (OCSC).

Selections for Orientation/Selection Camps (OCSCs)

Unless otherwise mentioned before the IOQ tests, a total of 35 students will be chosen for OCSC in Biology, Chemistry, and Physics, and 50 students will be chosen for OCSC in Astronomy.

If all students with the same grades at the last position in the respective IOQ Part II merit list are qualified for the OCSC, the final position is tied.

INBO Exam Pattern

The question paper will be available in both English and Hindi (option during enrolment)

A) There are 24 multiple-choice questions with only one correct answer. You will receive a three-point bonus for choosing the correct decision. A -1 point is deducted for each incorrect answer.

B) 8 multiple-choice questions with one or more correct answers. You must mark all of the correct alternatives and none of the incorrect ones to gain credit.

INBO Previous Year Papers

INBO Previous Year Question Papers are an important part in getting good grades. Candidates will have a better knowledge of the INBO Exam Pattern by practising these papers on a regular basis. Because a big number of students apply for IBO each year, competition is fierce. As a result, the students will gain from these question papers in terms of enhancing their speed and accuracy. Solving INBO past papers also helps students understand the marking methodology.

INBO Preparation Tips

Candidates are recommended to read the following INBO Preparation Tips before beginning their preparation:

Have a good understanding of the INBO Syllabus

Before beginning the preparation, it is critical to thoroughly review the complete syllabus. As a result, the share can be divided as needed.

Examination Pattern Analysis

It allows you to plan your study around the main themes and ensures that you cover the areas that are most important to you.

Consult the Study Materials

On the internet, you can find a variety of study materials for the INBO exam. Candidates must, however, be aware of how to use the proper study resources and sample papers.

INBO Sample Papers and Previous Year Papers can be used to prepare for the exam.

Every student preparing for INBO 2021 should solve sample papers and past year papers on a regular basis. It will help to increase their self-esteem.

Organizing your time

It's critical to stick to a daily schedule. It is critical to give each topic equal significance and time in order to achieve good grades. It is only achievable if good time management is used.

To all of the candidates, wish you the best of luck. Above all, enjoy the Olympiad since the trip can sometimes be more important than the destination. Check out our website for more information.
