It also provides a raw-score calculation system based on the marks assigned to correctly answered questions. Additional incremental weightage is attached to questions, beginning from 0.0001 and increasing with each question. This additional weightage is used to resolve ties while calculating Class, Zonal, and Olympiad ranks.

The Olympiad Rank includes students from India and abroad belonging to the same class, while the Class Rank includes students from different sections or divisions of the same class within the same school.

SilverZone iCSO Prizes and Awards

The Olympiad provides awards at international, zonal, state, and school levels.

The top three International Olympiad rank holders in each class receive cash prizes:
