What is the INAO Exam?

The Indian National Olympiad in Astronomy (INAO) is a national-level Olympic competition for students in grades 11 and 12 who wish to compete in the International Olympiad in Astronomy and Astrophysics (IOAA). INAO has conducted a test for CBSE. However, we must be familiar with the newest INAO exam pattern and question format before applying for the next INAO examination in 2024-25. We will be able to determine the examination's difficulty level as a result of this. As a result, we've covered the most recent exam pattern for INAO 2024-25 in this post.

Pattern and Distribution of Marks for the INAO 2024-25 Exam

All students must pass the National Standard Examination In Astronomy to be eligible for the INAO test (NSEA). Candidates who do not pass the NSEA test are automatically excused from INAO. There were 100 marks and two parts in the INAO previous year question papers, according to the INAO previous year question papers. Section A had 28 questions for 1 mark each, whereas Section B had 72 marks and 27 questions. Each wrong response gets minus one.

The organisation, HBCSE, has chosen to abbreviate the phases of the Astronomy Olympiad Program and perform the NESA and INAO examinations as a single paper because of the continuing pandemic situation in the country. This will be a three-hour test with two parts: Part 1 (National Standard Examination In Astronomy) and Part 2 (National Standard Examination In Physics) (INAO). The Indian Olympiad Qualifier will be held at this stage. The two stages are:

Part 1: National Standard Examination in Astronomy (NSEA)

An hour-long multiple-choice test will be given based on Class 10+2 Physics, Mathematics, and Elementary Astronomy. First, you must pass the NSEA segment to advance to the next round.

Part 2: Indian National Astronomy Olympiad (INAO)

There will be extensive questions in this two-hour session that meet the same INAO criteria as last year. If they pass the first portion, the candidate will only be considered for this phase. The score from this portion will determine who advances to the next phase, Orientation and Selection Camp.

Selection Procedure for Indian National Astronomy Olympiad

It is compulsory for all the students to qualify for the National Standard Examination In Astronomy to be eligible to appear for INAO. The eligible candidates are split into two batches - A and B. Students in Group A must be in class XII as of November 2023, while students in Group B must be in class XI or lower as of November 2023.

A total of 250 students will be chosen from each category for INAO stage II. As a result, 500 students will be chosen. Out of the total 500 students, only 35 will be selected for Orientation Cum Selection Camp.
