NSEJS 2020 Exam Pattern

Due to Covid 19 - The usual three-stage procedure for the selection of the teams to represent India at the International Olympiad that has been followed in prior years is now being shortened to a two-stage procedure as a one-time exception only for the academic year 2020 - 21. Read more about IOQ 2020-21.

Before starting with the NSEJS exam pattern, first, let us get an overview of the NSEJS exam. The National Standard Examination in Junior Science (NSEJS) is organised by the Indian Association of Physics Teachers whose objective is to discover and train the young generation to excel in the science subjects. NSEJS is the entry-level test for IJSO (International Junior Science Olympiad) and is specifically for the students of standards X or less. This exam is conducted every year in November, and only 300 candidates are selected to take part in the level 2 NSEJS exam.

The Indian Association of Physics Teachers (IAPT) decides the test pattern of NSEJS. Refer to the following table to get enlightened about NSEJS exam pattern IAPT.

NSEJS Exam Pattern 2020


Number of Questions with 1 Correct Option

Total Marks















Each right answer earns students 3 marks, while an incorrect answer leads to negative marking. One mark is deducted for every wrong answer.

For this year, along with these 60 questions, the NSEJS paper will constitute 10 other multiple choice questions, which have one or more correct answers. These 10 questions carry 6 marks each. Therefore, the total is 240 this time around.

To achieve a position among the 300 qualifying candidates, knowing the proper syllabus for NSEJS exam is also essential. The syllabus for this exam resembles one of CBSE classes 9 and 10.

Physics Syllabus

Physics is a crucial subject for NSEJS. This subject demands a considerable amount of preparation time as compared to others. Hence, students will need to have a detailed concept of the following topics from the subject -

  1. Electrostatics: Ohm’s Law, Resistance combination and Coulombs’s law.

  2. Sound: Node, Anti-node and Echo.

  3. Heat: Thermal Expansion, Anomalous Behaviour of Water and Radiation.

  4. Dimension: Units.

  5. Work, Power, Energy: Power and Efficiency.

  6. Fluid: Floatation.

  7. Simple Harmonic Motion: Simple Pendulum.

Chemistry Syllabus

According to the NSEJS exam pattern, students have to answer both theoretical and numerical questions in Chemistry. Therefore, they must prepare this subject accordingly. Following are the vital topics that students should prepare by heart to score considerably in this section.

  1. Analytical Chemistry

  2. Acids, Bases and Salts

  3. Mole Concept

  4. Non-metals and metals

  5. Carbon

  6. Gas Laws

  7. Periodic Table

Biology Syllabus

Biology is a theoretical subject and scoring is relatively easier. It is advisable for the students to study NCERT class 9 and 10 books to score well as per the NSEJS exam pattern.

Here are some chapters of Biology along with the essential concepts:

  1. Biodiversity: Monera, Chordates, Non-Chordates.

  2. Biotech: GMC

  3. Coordination and Control: Nerve Conductor, Endocrine System, Sympathetic Nervous System

  4. Cell Biology: Types of Cell, Cell Organelles

  5. Evolution and Heredity: DNA, DNA Finger Printing

  6. Human Health & Disease: Immunity

  7. Reproduction: Asexual Reproduction

Mathematics Syllabus

In comparison to the other three subjects, Mathematics can be challenging since it demands a lot of practice. For this subject also, the NCERT book is recommended because the NSEJS exam pattern primarily relies on the CBSE syllabus.

Following are the Mathematics chapters that form the syllabus of NSEJS:

  1. Arithmetic progression

  2. Geometric progression

  3. Circle

  4. Number System

  5. Ratio Proportion

  6. Triangles

  7. Trigonometry

  8. Linear Equation

  9. Permutation and Combination

  10. Quadratic Equation

  11. Quadrilaterals

All the NSEJS aspirants are advised to organise a daily routine so that they can cover the whole syllabus one month prior to the exam date. Doing so will leave ample room for revisions.

As mentioned earlier, there are no other alternative books other than NCERT, so students must follow the same. Moreover, students must also practise previous years’ papers released by the IAPT. This way, they can get an idea about repeat questions and the NSEJS pattern.

FAQ (Frequently Asked Questions)

Q1. Which Calculators are Allowed in the NSEJS Exam?

Ans. There are several calculator models, which can be used during INO exams only if they meet specific criteria. The first criterion is that calculators should not feature a graphing mode. Secondly, the display of the same should not contain above three rows, which is similar to matrix mode. Third, calculating devices should not have an integration function or equation solver.

Lastly, calculators should not store physical constant values in their memory. Some calculators that are allowed for usage are Casio fx - 220 plus, HP 10s +, Canon f - 502 G, Orpat Fx - 100D, Sharp EL - 501 X, TI - 30X IIS/IIB and various others which meet all the mentioned criteria.

Q2. What is the Eligibility for the NSEJS Exam?

Ans. The fundamental eligibility requirement is that candidates must be eligible to hold an Indian passport. His/her date of birth has to be within 1st January 2006 and 31st December 2007, inclusive of both the days. Next, he/she must be a resident and a student in India from 30th November 2018 or before.

Q3. Which are the Prescribed Books for NSEJS?

Ans. The NSEJS is a tough Junior Science Olympiad dedicated for pupils of classes 9 and 10. Some of the best-prescribed textbooks for NSEJS are NCERT and R.D Sharma for Mathematics, S.L Arora and H.C Verma for Physics, NCERT books up to Class 11 for Biology and O.P Tandon for Chemistry. Make sure to solve the various exercises at the end of each chapter in NCERT books. Doing so should help one attain a better grasp of the concepts. Besides studying from books, students must also solve sample question papers and appear for mock tests to attain a commendable score.
