IAO Exam Pattern 2025

Four to six different astronomy topics should be covered in the theoretical part of the challenges, according to the Methodical Commission of the Olympic Coordinating Council. High school students should be able to understand these questions using simple math instead of complex calculations. Examine the IAO Exam Pattern in the following table: 

The guidelines encourage that, as recommended by the Common Commission and the Olympic Coordinating Council, practical challenges should concentrate on one or two issues related to current studies at the host Astronomical Centre. According to the Common Commission of the Olympic Coordinating Council and the host Astronomical Center, observational tasks should include one to three difficulties, each of which can include several questions.

IAO Syllabus 2025

The student has to understand the IAO Syllabus and high school math and physics in order to answer the questions on the IAO question paper. The concept excludes spherical trigonometry, differential calculus, complex numbers, and integral equations. When the question is shown to the students during the exam, most of the material is eliminated. There are several data tables available to help them with the problems. 

• The exam's question content makes use of units that are common in astronomy and the physical sciences.

• Students have to use an appropriate unit in addition to the standard SI system.

• Students must correctly round off the final findings and include the appropriate number of significant numbers in their answers.
