How to join Science Olympaids?

Hi everyone, could someone please give me a short description of how I could join International Biology Olymapid or other STEM olymapids like chemistry, etc? How can I join and what are the deadlines?

The first step would be to see if your high school sponsors them. If it doesn’t, you could approach a teacher and ask if they can set testing up. Another option is to find a local testing center or another school that hosts the competitions. If you live in the U.S., there are bound to be multiple high schools in your state that hold olympiads.
