MOEMS Exam Guide
Monthly math olympiad contests building skills progressively from November to March
What Is the MOEMS?
MOEMS (Mathematical Olympiads for Elementary and Middle Schools) is a unique team-based math competition that spreads across five monthly contests from November through March. Each contest features just 5 questions, making the format approachable while still intellectually demanding. Over 100,000 students from approximately 6,000 teams worldwide participate each year.
MOEMS is divided into two divisions: Division E (Elementary, grades 4-6) and Division M (Middle, grades 6-8). Schools register teams of up to 35 students, and each team takes the same five contests on dates set by their school within a designated window each month. This flexible scheduling makes MOEMS one of the easiest competitions to administer for schools.
What sets MOEMS apart from other competitions is its progressive, monthly format. Rather than a single high-stakes exam, students build skills and confidence over five contests spanning five months. This structure mirrors how real mathematical ability develops — gradually, through consistent practice and exposure to challenging problems. Each contest serves as both an assessment and a learning opportunity.
The problems are short-answer (not multiple choice), requiring students to show genuine understanding rather than test-taking strategy. The difficulty level is carefully calibrated: the first 2-3 problems of each contest are accessible to most participants, while problems 4-5 challenge even strong students. Over a season, the cumulative difficulty exposes students to a broad range of mathematical topics and problem-solving techniques.
MOEMS is particularly well-suited for students who are new to competition math or who thrive in a team environment. The team structure means students can discuss problems after each contest, learn from each other, and build mathematical community at their school.
Format & Scoring
Everything you need to know about how the MOEMS works.
Score Ranges
| Level | Score Range | Percentile | What It Means |
|---|---|---|---|
| Developing | 0-8 (season) | Below 50th | Building problem-solving foundations. Many correct answers on easier problems. |
| Average | 9-14 (season) | 50th-70th | Consistent solver. Gets most ‘easy’ and some ‘medium’ problems right. |
| Strong | 15-19 (season) | 70th-90th | Strong competitor. Regularly solves 3-4 out of 5 problems per contest. |
| Excellent | 20-22 (season) | 90th-97th | Excellent performance. Rarely misses the first 4 problems. |
| Exceptional (Trophy/Patch) | 23-25 (season) | Top 3% | Near-perfect over 5 contests. Earns individual trophies or patches. |
Topics Covered
Approximate weight of each topic area on the MOEMS.
Operations, place value, estimation, fractions, decimals, and percents. MOEMS arithmetic problems go beyond basic computation — they test understanding of number properties and relationships.
Equations, expressions, word problems, and algebraic reasoning. Division E focuses on pre-algebraic thinking; Division M covers formal algebra including systems and inequalities.
Angles, area, perimeter, volume, and spatial reasoning. MOEMS geometry problems often require combining multiple concepts (e.g., finding a shaded area using subtraction of regions).
Systematic counting, arrangements, and basic combinatorial thinking. These problems reward organized, methodical approaches over intuitive guessing.
Divisibility, primes, factors, multiples, and remainders. MOEMS number theory problems are accessible but require careful reasoning about number properties.
Preparation Timeline
A month-by-month plan to build toward peak performance on exam day.
Take a diagnostic using past MOEMS problems for your child’s division. Identify which of the five topic areas need the most work. Start with 2-3 problems daily.
Work through structured preparation in each topic area. Focus on writing clear, correct answers (MOEMS requires exact short answers). Practice explaining reasoning.
Take Contest 1 and analyze results. Identify which problem types were hardest. Adjust preparation focus for the next month based on real contest experience.
Monthly cycle: take contest, review all problems (correct and incorrect), focus preparation on gaps revealed by each contest. Build momentum over the season.
Final contest. By now, your child should have a clear sense of their strengths. Go in confident. After the season, celebrate the growth over 5 months.
Score Interpretation & Percentiles
What does your child's score mean?
Honor Roll / Recognition
Students scoring 20 or above (out of 25) over the season typically earn individual recognition (patches or certificates).
Distinguished / Top Tier
Top individual performers across the country (23-25 out of 25 over the season) receive trophies. Top teams also receive awards.
A perfect score of 25 over the season (5/5 on all 5 contests) is achieved by a very small number of students nationally — typically fewer than 100.
Estimated National Percentiles
| Score | Approximate Percentile | Performance Level |
|---|---|---|
| 5 | ~25th | Building |
| 10 | ~50th | Average |
| 15 | ~70th | Strong |
| 18 | ~85th | Excellent |
| 20 | ~90th | Excellent |
| 23 | ~97th | Exceptional |
| 25 | ~99th+ | Exceptional |
Tips & Common Mistakes
Actionable advice from students and coaches who know the MOEMS inside out.
Read each problem twice before writing anything
MOEMS problems are concise and every word matters. Misreading a single condition (e.g., ‘at least’ vs. ‘at most’) leads to a wrong answer. With only 5 problems, accuracy is everything.
Show your work — even though only the answer is graded
Writing out your steps helps you catch errors and builds good habits. If you get a wrong answer, your written work helps you identify where you went wrong during review.
Use the monthly format to your advantage
Unlike single-day competitions, MOEMS gives you a month between contests to improve. After each contest, spend at least one session analyzing every problem — especially the ones you got right (were you lucky or did you truly understand?).
Practice writing exact answers in the required format
MOEMS is free-response, not multiple choice. Answers must be in the exact form requested. If a problem asks for a fraction, giving a decimal may not be accepted. Read answer requirements carefully.
The last problem of each contest is the hardest — budget time
With 5 problems in 25-30 minutes, you have 5-6 minutes per problem. Spend 3-4 minutes on problems 1-3, and reserve 8-10 minutes for problems 4-5.
Build a team study habit
MOEMS is a team competition. After each contest, gather your team to discuss solutions. Hearing how others approached the same problem expands your problem-solving toolkit dramatically.
