International Olympiad on Astronomy and Astrophysics (IOAA)

IOAA 2022 Date

The key aim of the IOAA is to promote an increased interest in Astronomy and related subjects, especially among young people, and to improve the development of international contacts between countries in promoting Astronomy and Astrophysics in schools. More bright high school students are predicted to be interested in studying Astronomy at the university level as the next generation of astronomers as a result of events like IOAA. The International Olympiad on Astronomy and Astrophysics(IOAA) 2022 Event will be the 15th IOAA, to be hosted by Ukraine in August 2022.

Stages of IOAA Exam

The Astronomy Olympiad programme is divided into four stages:

Stage I: National Standard Examination in Astronomy (NSEA),

Stage II: Indian National Astronomy Olympiad (INAO),

Stage III: Orientation cum Selection Camp (OCSC) in Astronomy,

Stage IV: Pre-departure Training Camp (PDT) for IOAA,,

Stage V: International Olympiad in Astronomy and Astrophysics (IOAA).


For IOAA 2022-23, the stage I National Standard Examination in Astronomy (NSEA) and stage II Indian National Astronomy Olympiad (INAO) are held in a single sitting for the examinee on the same day under the International Olympiad Qualifier in Astronomy IOQA.

The International Olympiad Qualifier Dates for Various Science Olympiads are Given Below


NSEA (IOQA) is now indefinitely postponed due to the resurgence of covid. IOAA is now indefinitely postponed due to the resurgence of covid. IAO is now indefinitely postponed due to the resurgence of covid. 


Vedantu makes it easier for candidates to check all the necessary details from one platform. They only need to keep a track of the website regularly for any further information. Updates regarding syllabus, registration process, the release of admit cards as well as important dates are all released on this platform. Candidates are advised to note all of it and keep themselves updated. This is essential because once a date is missed, he/she won’t be given a second chance for any procedure that the examination undertakes.


Candidates should register themselves with 200 Rs and keep the hard copy of the application form with them for future reference. As soon as the release date of admit cards are announced, candidates need to log in to their portal through their registration id and date of birth and get their admit cards downloaded from their dashboard. They are advised to keep a hard copy of it with them because they won’t be allowed in the hall without these papers. 


To have a solid preparation, one needs to know the syllabus entirely and follow it minutely. All the chapters are equally important so candidates are advised not to skip any. To participate in the Astronomy Olympiad, candidates must have a strong science base and analytical power so that all the conceptual questions can easily be solved by them.

 

One needs to constantly assess their progress by solving various sample papers available on the Vedantu website or the Vedantu app can also be installed in their cells to make the process simpler. These sample papers will give a lot of ideas to candidates on the pattern of questions that are usually made in these examinations. They will also come to know about the process to frame their solutions. Students should also get hold of previous year questions to make the concepts more clear.

4. Why are previous year papers important?

Previous year papers are essential to follow in any kind of examination since it gives a holistic idea on which part to focus more. Solving these papers will make candidates aware of their weaker areas and they can pay more attention to the same. Solved papers also prove beneficial as the solutions are compiled by research scholars and thus are authentically made solely for students' benefit. Candidates should make a fixed routine and adhere to it while solving these papers. This will allow them to practice all the chapters with equal importance.

5. Where can we find the previous year papers?

Last year IOAA papers are made available on the Vedantu platform and candidates can download them for free. Once downloaded they can be accessed in offline mode as well.
