The Unicus Science Olympiad (USO) is an international online competition for students in grades 1 to 11. Participants can take up to three practice tests before the final exam, which is held in the Summer.
The exam aligns with the current class syllabus, making it both relevant and practical. Students can register individually online, and free sample papers are available on the official website to help with preparation. USO is a great opportunity for students to strengthen their science skills and compete on a global level.
