NSO Class 12 Syllabus

The Science Olympiad Foundation administers the National Science Olympiad examination every year. This NSO exam is mostly focused on science-related themes. The exam is open to students studying in grades 1 to 12. Beginning with primary school, this exam aids in the discovery and development of future scientists, technicians, IT specialists, and other qualifications at a basic level. Olympiad exams develop a healthy competitive spirit among pupils, encouraging them to participate in national and international programmes. This type of exam encourages students to think from a wider angle and provides them with a once-in-a-lifetime opportunity to share their inventive ideas with the rest of the world.

Overview of the Examination

The National Science Olympiad Exam (NSO) is a scholarship exam designed to help students enhance their scientific reasoning and analytical abilities. The test is divided into two sections. Level 1 is the first, and students who qualify at this level can move to level 2. The NSO Olympiad test is divided into phases, which begin from grade 3. Students in Classes 1 and 2 will only take level 1 tests, and grades will be assigned based on their performance.

The test is an objective type with 35 multiple-choice questions for grades 1 to 4 and 50 for grades 5 to 12. To take the second level of the NSO exam, a student must rank in the top 5 percent of their respective class.

Examination Pattern for Class 12
