National Science Olympiad 2025

Science Olympiads, such as the National Science Olympiad (NSO), play a significant role in a student's life by providing various benefits and opportunities for growth. Students can enhance their knowledge and understanding of science by participating in these competitions. 

The National Science Olympiad (SOF NSO), conducted by SOF every year, evaluates the natural abilities and science skills of students from grades 1 to 12. This SOF Olympiad is a two-stage exam, and after qualifying for level 1, students have to attempt Level 2 to achieve merit rank and prizes. The SOF NSO is carried out on three dates for Level 1.

Students gain confidence in themselves by posing tough questions to themselves and analyzing various areas of science. If you too are interested to learn about what opportunities await you after attending the National Science Olympiad, this article has all the information regarding the Olympiad exam - NSO.

1.0What is the National Science Olympiad?

The NSO is a science competition for grades 1 to 12 students. It is organized by the Science Olympiad Foundation (SOF). The students travel to various universities during the National Tournament. This makes the students think about possible colleges for their bachelor's degree, gives them good memories, and opens their minds. The NSO awards students medals and trophies for outstanding performance in science education.

The SOF NSO Level 1 is held on three different dates, and schools are able to select the best date for taking the exam. There is a different question paper for each exam date.
