I can

"I am proud of being one of the candidates for Olympiad of Science (OSN). Phsyics, I prefer choose it than biology. My biology teacher ask me to take biology, but I don't do it. You must know that I am not smart as you think. I just be active in the class. I am proud because, I can get two option for this Olympiad. I would be the best. I think I can do it! Fighting! Nothing impossible. If they can, why I can't?"
