About NSO

National Science Foundation (NSO) is a competitive exam for school students, which is conducted once in a year. The exam is conducted at two levels for students of class I-XII. The exam aims to cultivate scientific reasoning and logical ability among the students.

NSO is conducted by Science Olympiad Foundation (SOF), an educational foundation established in 1996 to promote Science, Mathematics, General Knowledge, Logical Reasoning and English language skills among school children through various Olympiad examinations. In fact, NSO was the first Olympiad to be conducted by SOF. NSO is being conducted since 1996.

There are 2 levels of NSO. The paper pattern of NSO differs for both the levels at different class levels. The same is explained below:

There is no negative marking in NSO.

 

All the students of class I – XII are eligible for first level of NSO. There is no other eligibility criteria for NSO like minimum marks or anything alike. Students of any of the following categories are eligible for 2nd level of NSO:

  • Top 5% students of every class
  • Class wise top 25 rank holders from every zone and
  • Class toppers from each participating school provided at least 10 students from a class write the exam & score 50% qualifying marks. In case there is section wise registration, students with highest marks, irrespective of their section will qualify for the 2nd level.

Students from classes I and II do not need to appear for the 2nd level of NSO and are ranked based on their performance in the first level of the exam.
