The top 5% of students in each class who take the 1st Level test are:
Top 25 zone and class rank holders, as well as top rankers from each participating school, with at least 10 students taking the IMO test and scoring 50% qualifying marks.
Regardless of section, students with the best scores will qualify for the second-level IMO test if they register section-by-section.
The second-level test is only open to students in grades 3 to 12.
