I started coding in class 11. In my country, I only have one attempt to participate in International Olympiad in Informatics. IOI is my dream. Is it possible for me to participate in IOI 2023? If so, please suggest how can I prepare for IOI in one year. I know it sounds weird to prepare for IOI in one year. But please please suggest, how can I prepare for it. I am a pupil in my main Codeforces account. I am ready to work hard.
