Frequently Asked Questions on ISO 2022-2023

What is the ISO olympiad exam?

The International Science Olympiad (ISO), which began in 1989, allows students to demonstrate their abilities in science. Science has always been a topic that requires students to recall a lot of theories. As a result, pupils memorise everything and present it in their papers without understanding it. However, understanding the subject rather than memorising it will be beneficial in everyday life. It is a graded subject in which students must master ideas.

Are olympiads challenging?

Yes, olympiads are challenging, but with the right study guide and materials, achieving good results in the olympiad exams becomes extremely simple.

What is the syllabus for the ITO?

The Indian Talent Olympiad Organisation holds national and worldwide tests for state, international, ICSE, and CBSE boards in grades 1 to 10. Students must refer to their individual board patterns, Indian Talent Olympiad books, and previous years’ question paper sets, all of which are available on the website at The questions follow a multiple-choice format.

How many students from a school can take the olympiad exam?

A school must have a minimum of 40 students to participate in the Indian Talent Olympiad (ITO). There is no maximum number of participants.
