ARML LOCAL ROUNDDate:Oct. 28, 2023 (Saturday)
14:00-14:45(exam time: 45mins)

ARML Local Date:Apr. 21, 2024 (Sunday) 14:00-16:50


Since its inception in 1976, the American Regions Mathematics League (ARML) has brought together the top mathematics students in the US, involving over 2000 students and teachers every year. ARML brings together the nation's finest students. They meet, compete against, and socialize with one another, forming friendships and sharpen their mathematical skills. The contest is supported by many famous technology companies and top education institutions both inside and outside the USA. Top US high schools, such as the Thomas Jefferson High School for Science and Technology in Virginia, and the Academy for the Advancement of Science and Technology (AAST) in New Jersey attend the challenge every year as they value its academic merits.

ARML runs four contests during the year: the ARML Local contest, the ARML Power I, the ARML Power II and our main contests (ARML as well as IRML for international teams). Both the ARML Local and Power contests are organized by schools and students can sit in the exams within the school, which allow a wider range of students who are interested in mathematics to compete. ARML and IRML are co-hosted by Pennsylvania State University, the University of Georgia, Iowa State University, and the University of Nevada Las Vegas. In recent years, over 150 teams from 42 states as well as Canada, China, Macau, Korea, Vietnam, the Philippines have competed.

The ARML Local consists of multiple rounds, including a team round, an individual round and tiebreaker question, and three relay rounds (in which a contestant solves a problem and passes his/her answer to another team member, who then uses this answer to solve another problem). The ARML Power Round I&II Contest is proof-based, mirroring the power round in the main ARML and testing students’ mathematical skills as well as their ability to clearly explain their proofs and reasoning. Students who score well in the ARML Local in China will be invited to attend the ARML Power Round I Contest.

American Regions Mathematics League
Official ARML Local China Invitation Letter


On behalf of the executive board of the American Regions Mathematics League, I would like to invite mathematics teachers and coaches in China to organize teams for the ARML Local China , coordinated by ASDAN China. The primary ARML brings together the top mathematics students from around the country and is held in late May or early June every year, and this year we had over 150 teams of 15 students competing at four sites around the United States. In 2008, we decided to introduce ARML Local that could be completed at schools, and encouraged teams to invite other local schools to compete, essentially creating ARML Local contest sites around the country. We now wish to extend that invitation to schools throughout China to compete in ARML Local.

The contest format for ARML Local is similar to our main contest, mixing both team and individual elements. Teams consist of six students, and a school may field as many teams as they like. There is a 15 question Team Round that is worked together by each team for 45 minutes, followed by five pairs of Individual Round questions, with 10 Minutes per pair.

The final round is the Relay Round, where teams break up into groups of two, three, and six,and the answer to the first person’s question is needed to solve the second person's question, and so on. We will generate results for ARML Local, ARML Local China, and an aggregated results list so that teams can see how they stack up against teams from their own country and from around the world.

We welcome your participation in ARML Local China, and thank ASDAN China for coordinating the contest.

Coach and Participants

I have been participating in ARML for 8 years: 3 years as a student and 5 years as a coach. I recommend students to participate in ARML, as they can improve key skills such as team work and problem solving, which are very important for their future life and career. I'm excited to know that ARML Local is being introduced into China, because it gives Chinese students who love math the opportunity to easily participate in the American top math challlenge from their own cities.
ARML has taught and given me a lot, and I am lucky to have grown up in the San Francisco Bay Area, which is the best performing area in the ARML math competitions. Our ARML team often meets and practices at weekends, and I have made lots of friends with the same interests during these practices. Whilst studyingat MIT University, I will apply to be an ARML coach in the area, and I hope to share my experiences and knowledge with others.
I represented the New York City Team in ARML for 3 years. I loved it when I first participated in this challenge. Different from other challenges, ARML requires team cooperation, and all the rounds are very exciting. In my eyes, ARML attracts people who love math, so I have made friends with the top people in math,who have become my life long friends.


Language Chinese and English

Date: Apr. 21, 2024 (Sunday) 14:00-16:50(170 mins)

Location: Paper-based in partnering school

Competitors:A team of 6 high school students

Format and rules:

1) 14:00-14:45:Team round consists of 15 simple answer problems with 4 points for each correct answer and a maximum score of 60 points.

2) 15:00-15:50: Individual round consists of 5 rounds, each round begins with 2 simple answer problems lasting 10 minutes. At the end of the round, questions for the next round will be handed out. For each correct answer, 1 point will be awarded. The maximum score available is 60 points.

3) 16:00-16:10:Tiebreaker Round

a)10 minutes tiebreaker containing only one problem;

b)The tiebreaker is only for the individual ranking and has no effect on team round results.

4) 16:20-16:50:Relay Round

3 rounds, the maximum points for one team is 20 points. The answer to the first problem will be used to solve the second problem (the number is referred to as "the number you will receive"). Each person on a squad receives a different problem. Students may pass answers to their problems forward to the next student in their squad, and the final student in each squad may submit answers to the proctor after half or all of the time has elapsed in the round. Only the final answer submitted by each squad is eligible for points for a correct answer. If an incorrect answer is submitted to the proctor after a correct one, no points are awarded to that squad. You are NOT allowed to discuss with anyone.

a) For the first relay round (6 minutes), each team has been broken down into squads of 2 (A1+B1, A2+B2, and A3+B3). All correct answers are worth 2 points at 3 minutes and 1 point at 6 minutes.

b) For the second relay round (8 minutes), teams will be broken into two squads of 3 (A1+A2+A3 and B1+B2+B3). All correct answers are worth 4 points at 4 minutes and 2 points at 8 minutes.

c) For the final relay round (10 minutes), the team will compete on a single relay of six problems. All correct answer is worth 6 points at 5 minutes and 3 points at 10 minutes.
