Math Olympiad Contest Book Grade 6-8: 30 practice tests inspired by the style of MOEMS grade 6-8 Division M (unofficial guide)

This book consists of the author-created practice tests with author-prepared solutions. The book includes 30 mock practice tests (150 problems). Disclaimer: This book is designed to help students strengthen their problem-solving skills through practice problems inspired by the style of questions seen in mathematics competitions such as Math Olympiads for Elementary and Middle Schools (MOEMS).

About the authors: Hayk Sedrakyan has been an IMO medal winner and a professional mathematical Olympiad coach in the Greater Boston area, Massachusetts, USA. He has been the dean (and one of the main developers) of one of the largest math competition preparation programs in the USA. He has worked as a scientific researcher in Paris and holds a PhD in mathematics (optimal control and game theory) from Sorbonne University (UPMC), Paris, France. He is a Doctor of Mathematical Sciences in the USA, France, and Armenia, and holds three master’s degrees in mathematics from institutions in Germany, Austria, and Armenia. He also spent part of his PhD studies in Italy. Hayk Sedrakyan has worked as a scientific researcher for the European Commission sponsored SADCO project, has served as one of the team leaders at the Harvard-MIT Mathematics Tournament (HMMT), and was an invited speaker at Imperial College London. He participated in the International Mathematical Olympiads (IMO) in the United Kingdom, Japan, and Greece. He was elected President of the General Assembly and a member of the Management Board of the Cité Internationale Universitaire de Paris (10,000 students, 162 nationalities), and in the same year the institution was nominated for the Nobel Prize. He is the son and was one of the students of Nairi Sedrakyan. Nairi Sedrakyan is the winner of one of the highest international awards in mathematics (Erdős Award 2022, for having played a significant role in the development of mathematical challenges at the national or international level and which have been a stimulus for the enrichment of mathematics learning). He has been deeply involved in national and international Mathematics Olympiads, serving as President of the Armenian Math Olympiads and as a member of the IMO Problem Selection Committee. He is the author of one of the hardest problems ever proposed at the International Mathematical Olympiad (Problem 5 of the 37th IMO). This problem is considered one of the hardest in IMO history, as none of the members of the strongest teams (China, USA, and Russia) solved it correctly, and the Chinese national team (traditionally the strongest team) scored a total of 0 points on this problem and was ranked 6th overall instead of its usual 1st or 2nd place. The British 2014 film X+Y, released in the USA as A Brilliant Young Mind and inspired by Beautiful Young Minds (which focuses on an English math prodigy selected to represent the United Kingdom at the IMO), also states that this is the hardest problem ever proposed in the history of the IMO (minutes 9:40–10:30). Nairi Sedrakyan’s students have won around 20 medals at the International Mathematical Olympiad, including gold and silver medals. Nairi Sedrakyan also received a Gold Medal for his contributions to the world’s Mathematical Olympiads and scientific activities. Read more
