The SOF International Science Olympiad (Level 1) will be conducted on three different dates. Schools can choose one of the following exam dates.

SOF International Science Olympiad Exam Pattern

The SOF International Science Olympiad is conducted in offline mode and follows a multiple-choice question (MCQ) format. The exam evaluates students' understanding of scientific concepts, logical reasoning, and problem-solving skills. Students are expected to apply their knowledge to answer concept-based questions.

SOF International Science Olympiad Syllabus

The SOF International Science Olympiad syllabus is based on the science topics taught in the current class. It checks the understanding of science concepts, logical thinking, and problem-solving skills. The syllabus is different for each class and covers topics from the school curriculum.

The Science Olympiad Foundation releases the syllabus separately for every class and exam level. Students should check the official syllabus before starting their preparation so they can study the correct topics.
