Stages Required to Clear For Appearing in IOAA Exam

The IOAA exam is the final stage i.e. 5th Stage. To appear in this exam candidates need to clear the previous four stages i.e. Stage 1 (NSEA), Stage 2 (INAO), Stage 3 (Pre Departure Camp), Stage 4 (Orientation Cum Selection Camp), Stage 5 (International Olympiad).

What are the Participating Rules for Countries

The participating rules for the countries are given below:

  • Those students who will participate in the exam their age must be less than 20 years.
  • One team consist of total 5 candidates only.
  • The International board members are treated as contact persons for the participating countries in concern of the affairs of the International Olympiad on Astronomy and Astrophysics.
  • One team needs to be sent of the school by participating countries.
  • After the arrival of each team, the external head will hand over the organizers a list of contestants with their personal details such as DOB, first name, family name, home address and address of the school attended and certificates (in English) from the schools confirming their attendance and the year of competition.

Details Regarding Competition

The competition is divided into 2 parts i.e. theoretical and practical.

Theoretical CompetitionPractical Competition
This consists of short and long questions i.e. 15 short questions and 2/3 long answerThe organizer may provide a set of the task which consists of:
  • Paper-based practical problem
  • Computer-based problem
  • Observation
  • Planetarium simulation or combination of the four which is required to be solved within the duration of 5 hrs.

Note:

Time Allotted: 5 hrs (for theoretical) and 5 hrs (for practical)

Duration: 10 days including arrival and departure days.

While solving the problems, candidates can use non-programmable pocket calculators which is brought by themselves.
