International Science Olympiad [ISO] 2023

From our childhood, we have been habituated to writing exams all the time, and we keep attempting tests after tests. So how is ISO different from all those exams we keep writing? There is a reason why our parents push us to do everything in school. One of those reasons is writing in the Olympiad.

Since it starts from class 1, the students have the opportunity to conceptual learn at an early age. However, these exams are not particularly hard, especially the multiple-choice based questions. On this page, we will be updating the science olympiad details and information on the syllabus and sample papers. We also have a separate section that deals with the awards and prizes that are awarded.

International Science Olympiad 2023-24 Highlights

The International Science Olympiad (ISO), which was started way back in 1989, allows students to showcase their talent. Science has always been a subject that contains a lot of theories for students to remember. So students, in turn, end up memorizing everything and presenting it in the paper without understanding a thing. However, if you understand the subject instead of memorizing it, it will be helpful in day-to-day life. It is a scoring subject that requires students to master concepts.

One of the essential elements of mastering science is to visualize things happening in real life and relate them to the subject. As it is just theoretical learning, it is easier compared to other subjects. The International Science Olympiad (ISO) is one such platform where students have trained to attempt the exam by enhancing their conceptual learning. These exams are conducted twice a year. They have a good number of students attempting the ISO test every year.

The following table shows the highlights of the ISO 2023-24 exam.
