Q3. How Can You Access Resources and Study Materials for the IAO?
Answer. Look for online tools and blogs written by students who have taken the exams already. Schaum and related names are good choices for reference books. The Roger Freedman, Robert Geller, and William J. Kaufmann, is an exceptionally well-written textbook you may want to consider when reading about astronomy in the universe. If you need an introduction to astronomy, look for Astronomy: Principles and Practice, Fourth Edition (PBK): A.E. Roy, D. Clarke
