How the iTHO score is calculated
The raw score is computed by multiplying each correct answer by its corresponding base marks and summing the results.
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). Question 1 has a weightage of .0001, question 2 has .0002, and so on.
This weightage is utilised to resolve ties when calculating class, zonal and Olympiad ranks.
Try the tie-breaker
Tap questions to mark them correct and watch the weightage separate two equal raw scores.
Example Talent Hunt paper: 10 questions at 3 marks each.
6 of 10 correct. Two students with 18 raw marks are separated by which Talent Hunt questions they answered correctly.
Class rank
This encompasses all students from various sections and divisions of the same class within the same school.
Olympiad rank
This encompasses all students from India and abroad belonging to the same class.
One award per exam
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.
