What is the benefit of National Science Olympiad (NSO) ?

NSO picks questions very relevant to the current syllabus and its application.

It improves the students problem solving ability and challenges them to think analytically. Prepares them for future competitive exams by testing a student's aptitude as well as the knowledge of a particular subject. Provides exposure to students at the national as well as international platforms.

Eligibility Criteria

Age: Students of classes 1 to 12th are eligible to appear for the 1st level Olympiads. 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.

If students score the same marks in all sections, they are given the same rank.

Second level examination

In the second level exam, you are ranked on the basis of your total score.

In case two students score the same marks, their ranks are decided on the basis of the below points:

  • Higher marks scored in higher priority sections (second level exam)
  • Total marks scored in the first level exam
  • Higher marks scored in higher priority sections (first level exam)

If two students still score the same marks, they are given the same rank.

Level 2: The level 2 is conducted for students of class 3 to class 12. The qualifiers to second round would include the following:

  • Top 5% of candidates class wise who appear for the 1st  level exam. Due weightage to marks scored in different sections will be given. Each section is accorded separate weightage.
  • Zonewise top 25 rank holders class wise.
  • Class topper where at least 10 students from a class appear in the exam & scores 50% qualifying marks.

How to prepare

Study Material for NSO

  • Here are the books and online medium prescribed for NSO:
  • MTG NSO class wise Workbooks (For Class 1 to 10)
  • School Connect Online Video Material and Practice Notes
  • OSDS (Olympiad Skill Development System)
  • Previous Years' Papers
  • Olympiad's Book of Reasoning (for preparation for the reasoning section of NSO)
  • E-Quiz
  • If you’re a class 10 or 12 student, you can also refer to publications like Chemistry Today, Biology Today, Mathematics Today, Physics for You and MTG.
  • Most importantly login to School Connect Online and Select videos of your choice and  read,practice,mock tests to compete in the examination.

Preparation Tips for NSO:

  • NCERT thoroughly: Read your NCERT textbook and make a note of important concepts dealt in each of the chapters and practice several questions on these topics from the reference books you have. Take reference from School Connect Online with lot of videos and practice questions.
  • Get your foundation clear: Make your concepts crystal clear to yourself. Give the topics time it demands. How much you have studied is more important than how many hours you have studied. Take help from your teachers, friends to through your basics and clear your doubts.
  • Make proper notes: For easy learning and revision chits, make short notes and tricks for each chapter. Making notes in your language is very useful and hard to forget.
  • Be confident: Learn the concepts of each subject well in advance and be confident. It will help you to approach your goal with a positive attitude.
  • Do not lose sight of your goal: One of the major issues that the students face is losing sight of the goal.Exams like NSO demand perseverance and dedication throughout the preparation phase. Find methods to keep you motivated continuously.
  • Understand the standard of questions: If you are appearing for NSO, then expect questions of varying difficulty levels that test your logical and observational skills. There will be no direct questions.
  • Practice sample papers: Solving sample papers will give you a fair idea of the pattern of the questions asked. They are also good for improving the pace at which you attempt the paper in a limited amount of time. NSO sample papers can be obtained from the official website.
  • Relevant books: You must thoroughly study course books suggested by your school or board (ICSE, CBSE or State Board). In addition to this, you can refer the books available for Olympiad preparations to get a good rank in NSO.
