It depends on the education system in your country and region. Some education systems allow students to skip grades if they demonstrate exceptional academic ability or have completed additional coursework. In order to skip a few grades, you would need to prove your academic readiness to the school authorities and meet any special requirements. You should reach out to your school counselor or principal to discuss the possibility of skipping grades and the steps involved.
