The NSO consists of two stages: the National Standard Examination (NSE) and the International Olympiad Examination (IOE). The NSE is held in December, and the IOE is held in January.
To be eligible for the NSO, students must be Indian citizens and must be studying in a recognized school. Students can register for the NSO online through the SOF website.
The NSO is a challenging competition, and only a small percentage of students are able to qualify for the IOE. However, the NSO is a great opportunity for students to learn more about science and to compete with other students from across India.
