How can you prepare for National Astronomy Olympiad? What are the best resources and books to follow?

Being a participant in the National Astronomy Olympiad 2020 I guess I can better explain it. Answering this question I will consider that you are very amateur and beginner about the olympiad. Here I will be giving you my personal suggestions based on my experience and taking references from some sites and books. For Beginners: Astronomy lecture series by Michel van Biezen. His lectures are quite good. Initially, when I was unknown of some terms of Astronomy and basics, I watched his lecture and learned the basics concept which was quite helpful for me in understanding in-depth Astronomy and its terms. Check out the playlist of Astronomy. <a href="https://www.youtube.com/c/MichelvanBiezen" rel="noopener ugc nofollow" target="_blank">Michel van Biezen</a>. And also watch the lecture series of OSC Astrophysics. This series of lectures will cover up the major topic of Astrophysics which will be much helpful further to understand the base of Astrophysics.  <a href="https://medium.com/@dharamnathsah79/how-can-you-prepare-for-national-astronomy-olympiad-6f1527374228">Visit Now</a>
