**SOF national science OLYMPIAD NSO :-**

**National Science Olympiad (NSO)**

We help students of class 1 to 10 in preparation of NSO exam and courses through sample question and practice papers.

**About National Science Olympiad (NSO)**

### NSO is conducted at two levels:

**Level 1**: **The first level of the exam is organized in the respective schools of the participants during school hours only.**

– The level 1 exam is an objective-type test having a duration of 60 minutes and comprising 35 objective-type questions for classes 1 to 4 and 50 objective-type questions for classes 5 to 12.

– The exam consists of three sections for classes 1 to 10:

**Section-1: Logical Reasoning**

**Section-2: Science**

**Section-3: Achievers Section**

**Level 2: **

**The level 2 is conducted for students of classes 3 to12. The qualifiers to second round would include the following:**

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

**NSO Syllabus and Marking Scheme:-**

**Benefits:**

- NSO mainly emphasizes on application oriented learning which is very extremely in a longer run.
- You learn to answer in alternate ways.

**Eligibility:-**

- Students of classes 1st to 12th are eligible to appear for the NSO. There is no other eligibility criterion like minimum marks.
- The top 5% internationally ranked students class wise, the school toppers from each class (with minimum 10 students enrolled from particular class) and ten state toppers class wise are eligible to appear in the 2nd level exam.
