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.
Rank Structure:
Class Rank
This encompasses all students from various sections/divisions of the same class within the same school.
Olympiad Rank
This encompasses all students from India and abroad belonging to the same class.
Important Notes:
Each winner is entitled to one award per exam, receiving the higher-level award only. For example, international top three rank holders will receive awards based on their international ranks, and any awards based on their Zonal ranks will be passed to the next rank holder. Similarly, if a Zonal award winner also qualifies for a class award, the class award will be given to the next rank holder.
