National Science Olympiad 2024-2025

Introduction

The Science Olympiad Foundation (SOF) is an educational foundation and a non-profit organisation based in New Delhi, India which promotes science, mathematics, introductory computer education and English language skills amongst school children in India. It organises five Olympiads annually, namely the National Cyber Olympiad (NCO), the National Science Olympiad (NSO), the International Mathematics Olympiad (IMO) ,the International English Olympiad (IEO) and the International Sports & Knowledge Olympiad(ISKO). The SOF requires participants to register through their schools, rather than individually. We will focus on National Science Olympiad in this post.

This is organized to motivate student to strive for better scientific knowledge and deepen their understanding of the world.

The National Science Olympiad Level 1 will be conducted on 3 dates i.e.,. 18th Oct, 12th Nov & 3th Dec 2024.

How the Registration of Students worked

The NSO is open to the students of classes 1 to 12. Prospectus containing the Registration forms are sent to all schools registered with SOF. Schools not registered may also request for prospectus by sending an e-mail at [email protected]/phone call. Schools must return the registration forms to SOF, duly filled in and complete in all respects by the due date.

Roll Numbers for NSO

The school’s coordinating teacher will generate the students’ Roll Numbers as per the guidelines given. A copy of these roll numbers along with the Students’ Registration Sheet (SRS) and School Registration Form (SRF) should be sent to the Foundation’s office before the due date of submission of forms.

Foundation will register the applicant school and the students and dispatch question papers and guidelines for conducting the examination. Principals / teachers may please note that any school can be registered as a center for NSO. No fee is required from the institution to become a registered examination centre. A minimum of 10 students need to be registered from each school for feasibility reasons.

The NSO is conducted on three dates for Level 1. Each school may select a date for conducting the NSO as per its convenience. Each date of exam has a separate question paper.

Students should register through their respective schools only. Individual registrations by students are not accepted.

Fees for NSO

A nominal participation fee is charged from each student. Part of it is retained by the school for its expenses as exam center. Details about the fee / mode of payment etc. are given in the School Registration Forms sent to schools.

NSO FAQ

How does a student benefit by taking Olympiad exams?

Answer

Participants of Olympiads are ranked on the basis of marks obtained. Hence, after taking the first level of the test, students can judge themselves academically at four different levels – within the school, at city level, at state level and above all at International level.

Each student is provided a Student Performance Report (SPR). The SPR analyses the strong and weak areas of the student and also gives a detailed performance comparison of the student vis-à-vis other students at school, state and international level. Analysis of the student’s past 7 years’ performance is also provided.

Students are suitably awarded based on their international, State and School ranking. Prizes are announced annually and include cash awards, medals, gifts, certificates etc. The International toppers from each class are awarded at a grand prize distribution ceremony held in Delhi, presided over by an eminent personality. Prizes for state winners and school winners are sent to their respective schools. For the year 2015-16, a sum of Rs. Ten Crores will be incurred towards awards, felicitations, scholarships etc.

Who all are eligible to sit for the Olympiads?

Answer

Students of classes 1 to 12th are eligible to appear for the 1st level Olympiads. For National Cyber Olympiad, students from class 2 onwards are eligible to appear for the 1st level. There is no other eligibility criterion like minimum marks. Students who qualify for the 2nd level exam include.

(a) Top 5% of students’ class wise, who appear for the 1st level exam,

(b) State wise top 25 rank holders class wise, and

(c) Class toppers from each participating school where at least 10 students from a class appear in the exam & scores 50% qualifying marks. Students from classes 1 and 2 are not required to appear for the 2nd level exam and are ranked based on their performance in the first level exam. IEO is a single level exam.

I am interested to take part in the Olympiads. Tell me how will I come to know about the details of the exam?

Answer

All the relevant information is sent to the schools registered with us across countries, along with prospectus, registration forms, posters and other details before the first round of exams and then as the date and venue of the second level is decided, the information is sent to the relevant schools again. The students come to know about the necessary details from their school teachers or through the Foundation’s official website www.sofworld.org or through the foundations face book page facebook.com/sofworld.

Myself and few of my friends are interested to take part in the Olympiads but our school has not yet received any information regarding the Olympiad. What can we do?

Are there any special books which the participants should refer to for the NSO preparation?

Answer

In general, NCERT books/course books prescribed by the CBSE/ICSE/STATE BOARDS may be referred to for the preparation. We also have following books/materials for Olympiad preparation:

1)MTG Class wise Workbooks (For Class 1 to 10)

2)‘SOF Olympiad Trainer’ Mobile Apps

3)OSDS (Olympiad Skill Development System)

4)Previous Years’ Papers

5)Olympiads’ Books of Reasoning (for preparation for the reasoning section of Olympiads)

6)E-Quiz

Additionally, class XI and XII students can refer to the various publications like Chemistry Today, Biology Today, Mathematics Today and Physics For You and MTG books which contain useful matter including solved and model test papers of various National and International Olympiads.

My school does not want to register for the Olympiads, but I am very eager to write the exam. Can I do it on my own?

Answer

SOF does not encourage individual participation. Students have to register through their schools only.

7. I have cleared second level of the Olympiad and I have come to know that I am eligible for an award. I am studying in a different school / passed out from school and pursuing further studies. Will I come to know about the date?

Answer

As soon as we finalize the date and venue of the presentation ceremony, we send out the information to the schools concerned and also share the dates on our website and on our Facebook page. So please be in touch with your previous school or/and access of website regularly.

I have still not received my Roll No. / Admit Card / Participation Certificate. I have checked from my school authorities and they are also not in receipt of the same. Kindly advise what to do?

Answer

Please request your Principal / Science Teacher to inform us about the non-receipt of the above. We will send duplicate copies to your school as soon as we hear from them.
