Given that the SMO Open Section determines one’s eligibility for the IMO, students who hope to make it to the IMO team will need adequate preparation.
One of the best ways to begin preparation is to look at the syllabus and the type of questions tested from past year papers. By understanding the question format and what is within the scope of testing, students will be able to formulate their preparation plan and game strategy better.
To help students understand the knowledge points tested and problem-solving strategies, we have designed a 2002 – 2024 SMO Past Year Papers and Video Explanations Guidebook!
