The Homi Bhabha Center of Science Education (HBCSE) conducts the Indian National Biology Olympiad (INBO) every year to identify the young and eminent, would-be biologists. This exam is conducted as a second stage of the International Biology Olympiad. Students from all over the country participate in this exam every year and put in their best effort to showcase their capabilities in the subject. The exam is conducted at more than 15 centers across the country every year in the month of January. It is important for the students to know the exam pattern and question paper structure before appearing for the exam. This helps them in various aspects.

Negative Marking in the INBO Exam Pattern

The Indian National Biology Olympiad (INBO) is a competitive examination conducted for the students who have qualified in the first level of the IBO. The maximum score that a student can secure in this examination is 100. However, the students should be aware of the negative marking scheme followed by the Organizing Authority while evaluating the answer scripts. The scheme says that the total number of points scored by the students in the exam will be reduced by the number of incorrect answers attempted by the students. In other words, every incorrect answer will lead to a deduction of 1 point from the total score. 

FAQ (Frequently Asked Questions)

The Indian National Biology Olympiad is conducted to check the expertise of students in the field of Biology. To qualify for the INBO exam, the students must have secured a qualifying score in the first level of the International Biology Olympiad i.e. the NSEB (National Standard Examination in Biology). Students who are exempted from the NSEB on certain norms as mentioned during the enrollment page on the official website can also appear for the INBO.
