About

International Science Olympiad

The International Olympiad of Science organized by the SilverZone Foundation is an incredibly exciting event for young students who are passionate about science. The competition has been widely successful and received positive feedback from both teachers and students since its inception.

The iOS examination, which takes place annually, aims to test students' competency in science and is based on the syllabus provided by CBSE/ICSE and other State Boards. However, the examination paper also includes a section on Applied Science, which enables students to develop a deeper understanding of how science is applied in the real world.

By aligning with the ICSE, CBSE, and State board syllabuses, the international olympiad of Science provides a solid foundation for school children to thrive in Science. The competition helps students develop a strong knowledge base, critical thinking skills, and problem-solving abilities that will serve them well in their future academic and professional endeavors.

One of the most significant benefits of participating in the International Olympiad of Science is the detailed report students receive after the examination. The report offers students an opportunity to delve deeper into their strengths and weaknesses, identify areas for improvement, and motivate them to strive for excellence in their studies. Overall, the International Olympiad of Science plays a vital role in encouraging young students to pursue their passion for science and equipping them with the skills and knowledge they need to succeed in their academic and professional lives.

Raw Score Calculation

The raw score is computed by multiplying each correct answer by its corresponding base marks and summing the results. In mathematical terms: Raw Score = SUM (correct answer × subsequent base Marks).


Total Marks Calculation

Total Marks are determined by adding the raw score to the sum of the weightage of correct answers. Each question carries an additional weightage, starting from .0001 and increasing incrementally (.0002, .0003, and so forth). For instance, Question No. 1 has a weightage of .0001, Question No. 2 has .0002, and so on. This weightage is utilized to resolve ties when calculating Class/Zonal/Olympiads ranks.


Olympiad Rank

This encompasses all students from India and abroad belonging to the same class.


Class Rank

This encompasses all students from various sections/divisions of the same class within the same school.
