INAO Syllabus 2020

The INAO syllabus is the same as the NSEA Syllabus and includes the syllabus prescribed by CBSE in the NCERT books. The senior secondary level curriculum concepts are covered in the syllabus of the INAO exam. Though the syllabus is the same as that of the CBSE curriculum, the level of questions asked in the exam is of a higher standard. Most of the questions are application based and demand higher-order thinking skills. The questions asked in the National level Olympiads are of higher difficulty level than that in the International Olympiads. The topics covered from various subjects in the Indian National Astronomy Olympiad syllabus are summarized below.

Subject - Wise Syllabus for INAO Exam

INAO Syllabus varies across the subjects and the students are expected to be thorough with the following concepts from the subject ‘Elementary Astronomy’.

• Astronomy

• Gravitation

• Escape Velocity

• Kepler’s Law

• Miscellaneous

The important concepts to be learned by the students in Mathematics are the basics of Mathematics, Number theory, circles, orthogonality, parametric equations, the concept of complex numbers, lines, triangles, solid shapes and conic sections under Geometry, ellipse, parabola and hyperbola, limits, integration and differentiation under Calculus, L'Hospital's rule, permutations and combinations, Statistics and Probability (coin, dice and cards problems), quadratic equations and nature of roots, sequences and series, Sine and cosine rules, Napier’s analogy, straight lines, equations of lines, trigonometric identities and ratios, heights and distances. These are the most commonly appearing concepts in the question paper. However, the questions may also appear from other miscellaneous concepts in Mathematics.

The Most Commonly Covered Concepts in INAO Exam Syllabus from Physics Subject are:

• Capacitance, energy stored in a capacitor, parallel plate capacitors.

• Circular motion and kinematics of circular motion.

• Current electricity and its temperature dependence, use of Kirchoff’s current law and voltage law.

• Electromagnetic waves, electrostatic field, electric field, and electric potential.
