International Biology Olympiad (IBO)

The International Biology Olympiad helps promote awareness and interest in biology. On the official website, it states that students', "skills in tackling biological problems, and dealing with biological experiments are tested. Interest in biology, inventiveness, creativity, and perseverance are necessary." Each country that supports and takes part in IBO selects four students based on the results from its national competition.

In India, that qualifying contest is called the Indian National Biology Olympiad (INBO). To participate, your school must be registered by a licensed teacher or test administrator. This is to ensure that the contest is being administered fairly nationwide. If your school is not affiliated with INBO, nothing to worry. You can always take the initiative and request the school administration to register. There is some fee.

In the INBO, there are four stages. For details visit the official website.

International Chemistry Olympiad (IChO)

The International Chemistry Olympiad was founded on the basis that its contests, "should promote friendship and co-operation among the pupils, closer contacts among the young scientific workers, exchange of pedagogical and scientific experience," as stated on the official website. To qualify for this international competition, students must first compete in the Indian National Chemistry Olympiad (INChO). Afterwards, four participants are chosen to represent India internationally.

The theory part of the INChO examination is held in end-January/beginning February of every year. It is conducted by the Indian Association of Chemistry Teachers. School students (usually of standards 11, 12) first need to qualify the National Standard Examination in Chemistry (NSEC) held in November of the preceding year. Among the 30,000+ students who sit for the NSEC, only the top 1% are selected for the INChO.

About 55 students are selected from the written examination. Selected students have to then give a practical examination. A total of 30 students are selected from these to attend the International Chemistry Olympiad Training Camp (IChOTC), held at HBCSE, Mumbai. The team for the International Chemistry Olympiad is selected based on a rigorous procedure of theory and practical examinations at the IChOT

International Olympiad in Informatics (IOI)

The idea of initiating international olympiads in informatics for school students was proposed to the 24th General Conference of the United Nations Educational, Scientific and Cultural Organization (UNESCO) in Paris by the Bulgarian delegate Professor Blagovest Sendov in October 1987. This plan was included into the Fifth Main Program of UNESCO for the biennium 1988-1989 (Section 05 215). In May 1989, UNESCO initiated and sponsored the first International Olympiad in Informatics (IOI). (Quoted from the IOI'89 and IOI'92 Report). The first IOI was held in Bulgaria in 1989.

The Indian Computing Olympiad is a nationwide competition organized annually by IARCS. The goal of the competition is to identify school students with outstanding skills in algorithms and computer programming.

The Indian Computing Olympiad is open to all school students across the country, from any school board. Any student registered in school upto class 12 during the current academic year is eligible. There is no lower age limit for participation.

The Indian Computing Olympiad is used to select the team of four students to represent India at the International Olympiad for Informatics (IOI). IOI is one of the twelve international Science Olympiads held annually. Other prominent Science Olympiads include Mathematics, Physics, Chemistry, Biology and Astronomy.

International Linguistics Olympiad (IOL)

The IOL is one of 12 International Science Olympiads for secondary school students, and has been held annually since 2003. Each year, teams of young linguists from around the world gather and test their minds against the world's toughest puzzles in language and linguistics.

No prior knowledge of linguistics or languages is required: even the hardest problems require only your logical ability, patient work, and willingness to think around corners.

India first competed in the IOL in 2009, and has competed in 8 olympiads. They most recently competed in 2016. They have sent 40 participants in 10 teams.

International Math Olympiad (IMO)

The International Mathematical Olympiad (IMO) is the World Championship Mathematics Competition for High School students and is held annually in a different country. The first IMO was held in 1959 in Romania, with 7 countries participating. It has gradually expanded to over 100 countries from 5 continents. The IMO Advisory Board ensures that the competition takes place each year and that each host country observes the regulations and traditions of the IMO.

The Mathematics Olympiad is conducted under the aegis of the National Board of Higher Mathematics (NBHM).

International Physics Olympiad (IPhO)

 The International Physics Olympiad (IPhO) is an international physics competition for secondary school students. The first such competition was organised by Prof. Czesław Ścisłowski in Warsaw (Poland) in 1967. Since that time the International Physics Olympiads have been organised, with few exceptions that will be discussed later, in a different country every year.

The Indian National Physics Olympiad (INPhO in short) is the second stage of the five-stage Olympiad programme for Physics in India. It ultimately leads to the selection in the International Physics Olympiad.

INPhO is conducted on the last Sunday of January (or on the first Sunday of February), every year, by the Homi Bhabha Centre for Science Education. School students (usually of standards 11 and 12) first need to qualify the National Standard Examination in Physics (NSEP) held on the last(or second last) Sunday of November of the preceding year. Among over 40,000 students[1] appearing for the examination at almost 1400 centres across India, around 300 to 400 students are selected for INPhO based on their scores and also based on regional quotas for the states from which they appear. Different state-wise cut-offs exist for selection to INPhO. INPhO serves as a means to select students for OCSC (Orientation Cum Selection Camp) in Physics, as well as to represent India in the Asian Physics Olympiad (APhO).
