# National Science Olympiad (NSO) – All You Need To Know

## What is NSO?

National Science Olympiad (NSO) is a yearly competitive exam conducted for school students. Organized by Science Olympiad Foundation (SOF), this exam aims at cultivating scientific reasoning and logical ability among the students through a rigorous test. The Foundation primarily envisions the scientific curiosity and vigour in young students through competitive exams. Read on to find out more about NSO.

**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 1
^{st}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.

**Note-**

- Questions of level-I Olympiad exams will be 60% from the current class syllabus and 40% from the previous class syllabus, e.g. Class-7 NSO exam will have 60% questions from class-7 syllabus and 40% questions from class 6 syllabus.
- Questions of level-II Olympiad exams will be from current class syllabus only.
- Questions in ACHIEVERS SECTION will be from current class syllabus only.

**How should I prepare for NSO?**

**Understand the pattern of NSO:**You can visit the official website to learn the exam pattern for you corresponding class. Broadly, the exam comprises of 50 questions that are divided into three sections – Verbal and Non-verbal Reasoning, Science, and High order thinking questions. It is advised that you know this pattern well to streamline the preparations.**Understand the standard of questions:**If you are appearing for NSO, then expect questions of varying difficulty level. The questions test logical and observational skills of the students besides the conceptual knowledge. There will be no direct questions but rather an application of a previously studied concept is more likely to form the base of a question.**Know the relevant books:**You must thoroughly study course books suggested by your school board (ICSE/ CBSE/ State Board). In addition to this, you can refer to books available for Olympiad preparation to get a good rank in NSO.

The books prescribe for NSO are as follows:

- MTG NSO class wise Workbooks (For Class 1 to 10)
- SOF Olympiad Trainer’ Mobile Apps
- OSDS (Olympiad Skill Development System)
- Previous Years Papers
- Olympiad’s Book of Reasoning (for preparation for the reasoning section of NSO)
- 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.

**Practice sample papers:**If you are appearing for the first time or are regulars at NSO, procure previous years papers beforehand. Solving the sample papers will give you a fair idea of the pattern of questions asked. They are also good for improving pace for attempting paper in the given time. The sample papers can be obtained from the official website.

## Where can I find previous years’ papers?

Sample Papers are sent to all schools registered for Olympiad exams. SOF website also contains these papers http://www.sofworld.org/nso/nso-exam/sample-papers.html. Sample papers sent to the schools prior to the first level test are helpful and can be used for both levels of Olympiad exams. There are no officially available previous years’ papers.

**When do I qualify?**

2nd level exam held for Science Olympiads (NSO) for students from class 3 onwards. In case two or more students score same total marks, ranks will be awarded to student scoring higher marks in sections accorded higher priority, as under:

PRIORITY | SECTION |

1 | Achiever’s section |

2 | Science |

3 | Logical Reasoning |

For class 11th and 12th | |

1 | Achiever’s Section |

2 | Physics |

3 | Chemistry |

4 | Mathematics/Biology |

In case two or more students score equally in all sections, they will be accorded same rank.

**CRITERIA FOR RANKING IN 2nd LEVEL OLYMPIAD EXAMS:**

In case of level 2 exams, ranks will be accorded on the following criteria:

Total Marks scored in level 2 exam. In case two or more students score same number of marks, ranks will be determined on following criteria:

- Marks scored in sections in level two exam accorded higher priority.
- Total marks scored in Level one exam.
- Marks scored in sections, in level one exam, accorded higher priority.

In case two or more students score same marks under all the categories above, they will be awarded the same rank.

**CRITERIA FOR RANKING- SINGLE LEVEL OLYMPIAD EXAMS:**

For class one & two students appearing in NSO ranks will be accorded on the following criteria.

- Marks obtained in the exam.
- In case two or more students score same number of marks, ranks will be determined on the basis of marks scored in sections accorded more priority.For ICSO, incase of tie, marks scored by a student in class 10 may be considered to determine rank.
- For other olympiads marks scored by a student in previous class may be considered to determine rank.
- In case two or more students score same marks under both the criteria above, they will be awarded the same rank.
- In case of any confusion decision of the Academic Council will be final binding.
