Self-study is not impossible. Many of my high school classmates are self-taught. They buy reference books and topics and then train them. Not bad.

For you. I suggest that you should consult your teacher when you buy books (you don't have to find a class, as long as you are a good teacher). Because these things change greatly with time and place, I don't know.

And as the one above said, it's really cool to learn something first. However, it's a bit difficult for you to take the high school Olympics first. I think you can try to teach yourself the contents of junior high school. I think what you learn first will be very helpful for you to learn the Olympics.

Speak my mind

I hope I can help you. Happy new year!
