International Mathematics Olympiad (IMO)
The SOF IMO Olympiad, a renowned Mathematics competition, serves as an examination to gauge students’ Mathematical comprehension and potential. By taking part in this IMO Olympiad exam 2025, students can assess their grasp of the subject matter and their proficiency in solving a variety of problems on school, local, zonal, and global scales. To participate in the SOF IMO (International Mathematical Olympiad), students have the option to register individually up to 15 days before the test date.
Founded in 1959 and inaugurated in Romania, the prestigious Mathematics competition, known as the IMO (International Mathematical Olympiad), has been an annual event ever since. Throughout the years, it has expanded substantially, serving as a platform for students to demonstrate their mathematical prowess and knowledge. Drawing participants from more than 100 countries across Africa, Asia, Europe, North America, South America, and Oceania, the competition has achieved global prominence.
In the syllabus of the (International Mathematical Olympiad) IMO exam 2025, both Levels I and II cover the same topics and chapters. However, there is a noticeable increase in the difficulty level as students progress from Level I to Level II. The International Mathematical Olympiad (IMO) comprises two distinct levels of competition. This year, the eagerly awaited (International Mathematical Olympiad) 66th IMO Olympiad 2025 is scheduled to be held in July (10 July 2025 – 20 July 2025) in Sunshine Coast, Queensland, Australia, offering a stage for talented young mathematicians to exhibit their skills and engage in friendly competition with their peers.
