What is the NSEJS Exam?
Introduction to NSEJS
The NSEJS (National Standard Examination in Junior Science) is the first stage in the selection process for the International Olympiad in Science for students up to class 10 in India. It’s organized by the Indian Association of Physics Teachers (IAPT) and is one of the most prestigious competitive exams for science students below the age of 15.
NSEJS aims to promote interest in science among students and identify the most talented individuals who can represent India at the International Junior Science Olympiad (IJSO). The competition is fierce, but the rewards are phenomenal. Students who qualify the NSEJS gain recognition, scholarships, and opportunities to train with India’s best mentors.
The exam is usually held once a year, and qualifying this stage is the first major hurdle before moving on to Indian National Olympiad (INO) and then the Orientation cum Selection Camp (OCSC). Eventually, top students are selected to represent India on the global stage.
Objective of the Exam
NSEJS is not your typical school exam. Its main goal is to:
- Identify scientific talent early.
- Promote deeper understanding of scientific concepts beyond the textbook.
- Encourage analytical and logical reasoning skills in young students.
- Create a pipeline for nurturing international-level talent in Science.
Students are tested not only on their knowledge but also on how they apply it in unfamiliar situations. That’s what makes NSEJS so challenging—and so rewarding.
Why is NSEJS Important for Students?
Gateway to International Olympiads
One of the biggest reasons students take NSEJS seriously is because it opens doors to prestigious international platforms like the IJSO (International Junior Science Olympiad). Representing India on such a global platform is not just a matter of pride—it’s also a huge boost to any student’s academic and professional future.
The road from NSEJS to IJSO goes through several rigorous stages:
- NSEJS (Stage 1)
- INO (Stage 2)

The eligibility rules are designed to give a fair chance to all science enthusiasts across the country.
Detailed Syllabus of NSEJS Exam
The syllabus of NSEJS is broad and goes slightly beyond the school curriculum of CBSE Class 9 and Class 10. It includes four main subjects—Physics, Chemistry, Biology, and Mathematics—interwoven to test your applied knowledge.
Let’s break it down subject-wise.
Physics Topics
Physics in NSEJS is a mix of conceptual and numerical problem-solving. The topics typically include:
- Motion and Forces
- Work, Energy, and Power
- Gravitation
- Sound and Light
- Electricity and Magnetism
- Heat and Thermodynamics
- Basic Mechanics
- Pressure and Fluids
Questions are based on real-life scenarios, and you must know how to apply formulas, not just memorize them.
Chemistry Topics
Chemistry problems in NSEJS test your understanding of substances, reactions, and molecular structure. Common areas include:
- Structure of Atom
- Periodic Table
- Chemical Reactions
- Acids, Bases, and Salts
- Metals and Non-Metals
- Carbon and its Compounds
- States of Matter
- Environmental Chemistry
Emphasis is on conceptual clarity, so simply mugging up facts won’t help.
Biology Topics
Biology covers both botany and zoology topics from Classes 9 and 10, including:
- Cell Biology
- Plant and Animal Tissues
- Human Body Systems (Respiratory, Circulatory, Digestive, Nervous)
- Genetics and Evolution
- Reproduction
- Health and Diseases
- Diversity in the Living World
Real-life applications and diagrams play a big role in the kind of questions you’ll face.
Mathematics Topics
Math isn’t the main focus in NSEJS, but it still holds importance. The questions usually test logical reasoning and numerical ability.
- Number Systems
- Algebra and Linear Equations
- Geometry
- Mensuration
- Probability and Statistics
- Graphs and Functions
You don’t need to be a math wizard, but strong basics will give you an edge in physics-based numericals too.
NSEJS Exam Pattern and Marking Scheme
Question Format
The NSEJS exam format is designed to assess both depth and breadth of understanding. Here’s how it usually looks:
- Total Questions: 80 multiple-choice questions
