If you’re new to the Olympiad, take a look at the syllabus to see the covered topics!

After that, we recommend checking out our past exams as well as past IOAA exams.

Some other resources we recommend are:

  • An Introduction to Modern Astrophysics by Bradley Carroll and Dale Ostlie
  • Fundamental Astronomy by Karttunen et. al.
  • sells used textbooks at a low price and in great condition.
  • edX, Coursera, and other online educational platforms often have astronomy or astrophysics related courses.
  • Stellarium is one of many resources (but probably the best) for studying constellations and Deep Sky Objects.
