INAO Syllabus
The Homi Bhabha Centre for Science Education, in partnership with the Indian Association of Physics Teachers (IAPT), is responsible for organizing the national Olympiad examination known as the Indian National Astronomy Olympiad (INAO). The INAO exam is often conducted in late November. Only candidates who passed the first round, the NSEA, are qualified to take this second round.INAO Syllabus

Syllabus for INAO Exam
The goal of the Indian National Astronomy Olympiad is to stimulate applicants’ interest in astrophysics and astronomy. Candidates for the International Olympiad in Astronomy and Astrophysics (IOAA) are prepared for this national competition. To take the exam and advance to the next level, candidates need to have a solid comprehension of the material covered in the INAO exam syllabus. The conducting authority hasn’t, however, offered a comprehensive INAO syllabus. Up to CBSE Class 12 level, the topics mainly cover mathematics, physics, and elementary astronomy.INAO Syllabus
Subjects for Exam
The program includes physics, mathematics, and astronomy as disciplines. The key ideas from each subject area covered in the INAO exam syllabus are listed here.
Syllabus for Physics
A comprehensive study plan is necessary to be ready for the INAO physics exam because the syllabus is lengthy and covers a wide range of complex topics, from electromagnetics to thermodynamics.
Topics covered in physics are:
- Capacitance, energy stored in a capacitor, parallel plate capacitors
- Circular motion and kinematics of circular motion
- Current electricity and its temperature dependence
- Kirchoff’s current law and voltage law
- Electromagnetic waves, electrostatic field, electric field and electric potential
- Measurement errors and maximum permissible error
- Geometrical optics, Plane and Spherical Mirrors, Optical Instruments and Eye defects
- Kinematics, Thermodynamics and Kinetic Theory of Gasses
- Fluid Mechanics and Archimedes Principle
- Heat Transfer, Steffen’s and Wien’s Law
- Force and Newton’s laws of motion
- Heating, magnetic and chemical effects of electric current
- Projectile Motion, relative motion in one and two dimension
- Surface Energy and surface tension
- Units and dimensions of physical quantities
Syllabus for Maths
The INAO mathematics curriculum covers a wide range of topics from elementary school to twelfth grade, from basic to advanced. Many problems from the mathematics section can take up most of your exam time on the INAO exam.
Topics covered in mathematics are:
- Number Theory and Complex Numbers
- Lines, Triangles, Solid shapes and Conic Sections
- Circles, Ellipse, Parabola and Hyperbola
- Orthogonality, Parametric equations, Quadratic Equations
- Integration and Differentiation
- Permutations and Combinations
- Straight Lines, Equation of Lines, Trigonometric Identities, Sine and Cosine Values
- Nature of Roots, Sequences and Series
- Statistics and Probability
Syllabus for Astronomy
The questions are almost entirely generic, needing only a rudimentary knowledge of constellations and astronomical events. We advise looking at star charts to learn how to recognize stars and constellations. Verify the candidates’ knowledge of latitudes, longitudes, and the planets’ positions in space.
Topics covered in astronomy are:
- Astronomy
- Gravitation
- Escape velocity
- Kepler’s law
- Miscellaneous
Five Stages of Exam
The Astronomy Olympiad Programme is divided into five parts.
Stage 1: National Standard Examination in Astronomy (NSEA)
Stage 2: Indian National Astronomy Olympiad (INAO)
Stage 3: Orientation cum Selection Camp in Astronomy (OCSC)
Stage 4: Pre-departure Training Camp (PDT) for IOAA
Stage 5: International Olympiad in Astronomy and Astrophysics (IOAA)
