NSO- About SOF

The Science Olympiad Foundation (SOF) organizes the NSO on a yearly basis. The Foundation's mission is to promote a scientific mindset among students. It is an educational organization that supports students' intellectual development through various competitions and Olympiads. For more than two decades, the organization has worked to promote a scientific mindset among students across the country through innovative activities. National Cyber Olympiad, National Science Olympiad, International Mathematics Olympiad, International English Olympiad, International Company Secretaries Olympiad, and International General Knowledge Olympiad are some of the major competitions organized by SOF.

Eligibility- NSO

There are two levels in the Olympiad exam, Level 1 and Level 2. 

Level 1:

For the Level 1 exam, there are no specific requirements. Students that belong from grade 1 to 12 are eligible for this opportunity. Because there are no minimum score criteria, the Olympiad is open to all school students.

Level 2:

Only students who do well in the Level 1 exam will be qualified for the Level 2 exam. Students who meet the following requirements will be taken into consideration:

The top 5% of students per class who took the Level 1 exam. 

Each class's top 25 zone-wise rank holders

Top students from each participating school, where at least 10 students from a class, take the exam and score 50% or more.

However, students that are in classes 1 and 2, are not required to take the Level 2 exam. They will be ranked simply on the basis of their achievement in the Level 1 exam.

National Science Olympiad

The National Science Olympiad is held every year to encourage students to improve their understanding of scientific facts and data, as well as their reasoning, analytical, and problem-solving ability.  

To score good marks in this exam, students need to study hard. To help the students, Vedantu has provided study materials to prepare for the exam. The study materials include syllabus, previous year papers, sample papers, and important questions. Also, information about the exam, its registration, dates, etc are mentioned below. Students can access them from the links given below:

The National Science Olympiad (NSO) is a science competition open to children in grades one through twelve. It is organized by the Science Olympiad Foundation (SOF) with the purpose of identifying and nurturing future scientists, technicians, and IT talent in secondary schools.

NSO participants are ranked based on their 1st Level performance. Students can evaluate themselves academically at four different levels after taking the first level of the test: within the school, at the local level, at the state level, and, most importantly, at the international level.

The following students are eligible for the 2nd level exam:

  • the top 5% of students in each class who take the 1st level exam, 

  • the top 25% of students in each state who take the 1st level exam, and 

  • when at least 10 students from a class take the exam and obtain 50% qualifying marks, the class topper from each participating school

Students in classes 1 and 2 are not required to take the second level exam and are instead ranked based on their first-level performance. The NSO is a one-level test.

Tips to Score High Marks in NSO Olympiad 

Since its inception, the NSO exams have been a fantastic means to assess a student's knowledge of many disciplines. Although an NSO Olympiad Test covers nearly the same material as a school-based exam, the format and method of the Olympiads are significantly different, making them more rigorous and better assessors of a student's progress.

nsos are used to encourage students to study harder in preparation for upcoming competitive tests and to help them acquire conceptual content. Here are a few pointers to help you evaluate your progress and better prepare for your Olympiads:

  • Make a List

Students frequently rely solely on the study materials provided for their Olympiads. They look through them exhaustively, believing that this is sufficient; nevertheless, it is not. Making notes as you study aids in your understanding of the material. It's always a good idea to jot down the points that appear important. When you're revising for your Olympiads, these quick notes come in handy because you don't have to read everything twice.

  • Understand the Syllabus

The first item on your to-do list should be to familiarize yourself with the syllabus for your Olympiad. A good understanding of the syllabus allows you to effortlessly move through the topics, making the task of covering them more manageable. You can see what themes your school syllabus and your Olympiad syllabus have in common, which will help you figure out which things you should focus on more in order to be well prepared for your Olympiad tests.

  • Begin Early

When it comes to studying for an exam, especially an Olympiad, early is never enough. The more prepared you are, the better. Putting off studies for a later date is not a good idea. Procrastination has its own set of consequences. Olympiads assess your conceptual understanding, which is entirely reliant on your knowledge of the fundamentals. Covering the fundamentals and then delving deeper into the subject are not something that can be crammed into last-minute preparations. If you have to start small, do so, but always begin early when preparing for your Olympiads.

  • Perfection Comes with Practise

It is much easier to prepare for Olympiads now that there is an abundance of preparatory books available on the market and the internet. A student must obtain as many sample question papers, Olympiad: Topic Page and previous years' Olympiad question papers as possible in order to acquaint oneself with not only the pattern of the test, but also to practise. Practicing guarantees that your problem-solving speed improves, which can be a significant benefit on Olympiad day. Practicing also boosts confidence, and the more problems you solve, the more you understand the idea.

  • Self-Assessment

When it comes to preparing for an Olympiad, simply studying and practicing is never enough. One must examine oneself to establish one's own strengths and shortcomings in order to determine where more effort is required and where it is not. Timing yourself while solving sample papers and evaluating yourself objectively helps you examine your performance and mentally prepare for the Olympiad.
