International Science Olympiad Syllabus 2022

The International Science Olympiad (ISO) syllabus for the different exams is called International Science Olympiad. Different levels have various International Science Olympiad (ISO) syllabus. The specialty of this syllabus is that there are also experimental concepts and theoretical concepts that students should understand as these are asked in the different International Olympiads.

International Science Olympiad (ISO) syllabus for NSE and INO for the same subject is similar. The table below gives the syllabus for different subjects.
