The Gauss math competition is running right now — from Monday 11 May to Friday 22 May 2026. If your child is sitting it this week or next, the preparation window is not closed. What a student does in the days immediately before the contest can meaningfully affect their performance, and what they do in the days after can set them up for stronger results in future competitions. This guide covers exactly what to do between now and the contest, what to do on the day itself, and how to use the result productively whatever it turns out to be.
What is the Gauss math competition?
The Gauss math competition is a 25-question multiple choice mathematics contest for Grade 7 and Grade 8 students, run by the Centre for Education in Mathematics and Computing at the University of Waterloo. It is the most widely sat school mathematics competition in Canada and the entry point to the Waterloo CEMC contest series — the same series that leads through Pascal, Cayley, Fermat, and Euclid to university admissions consideration.
The contest is 60 minutes, scored out of 150 using a weighted system (5 points for questions 1 to 10, 6 points for questions 11 to 20, and 8 points for questions 21 to 25), and there is no penalty for wrong answers. Every student should attempt every question.
For a complete overview of the Gauss math competition including format, scoring, topics, and the full CEMC pathway, see Gauss Math Contest: The Complete Guide for Canadian Students and Parents.
If your child has not yet sat the competition — what to do right now
The most important thing to understand about preparation in the days immediately before a competition is that this is not the time for intensive study. Trying to learn new topics or work through difficult problems the night before the Gauss creates anxiety without meaningfully improving performance. The goal this week is consolidation, confidence, and readiness — not new learning.
Day one or two before the contest — light review only
The most effective use of the one or two days immediately before the Gauss math competition is a focused review of the things your child already knows, not an attempt to learn anything new.
Spend 20 to 30 minutes reviewing these specific items:
Benchmark fractions and percentages — these should be instant recall, not calculation. The percentage equivalents of 1/4, 1/3, 2/3, 3/4, 1/5, 2/5, 3/5, 4/5, 1/8, 3/8, 5/8, 7/8 should come to mind without working them out. For a full reference table of the benchmarks worth knowing, see Percentage of 11 out of 15: How to Convert Scores to Percentages Gauss Contest Guide.
Key geometry formulas — area of a triangle, rectangle, circle, trapezoid, and parallelogram. Perimeter of standard shapes. The Pythagorean theorem and the three most common Pythagorean triples (3-4-5, 5-12-13, 8-15-17). For a complete formula reference, see Area and Perimeter Worksheets: How to Solve Every AMC 8 Geometry Problem.
Angle facts — angles on a straight line sum to 180°, angles at a point sum to 360°, vertically opposite angles are equal, co-interior angles in parallel lines are supplementary. These appear on almost every Gauss geometry question. For a full review see Supplementary Angles Explained: Definition, Examples and AMC 8 Problems.
Divisibility rules — for 2, 3, 4, 5, 6, 8, and 9. Being able to instantly check whether a number is divisible by these values saves time on number theory questions.
The nth term formula — for arithmetic sequences: first term + (n-1) x common difference. This applies to growing patterns, shrinking patterns, and many word problems. See Growing Patterns, Repeating Patterns and Pattern Rules: A Gauss Contest Guide.
Unit rate setup — knowing that rate problems always become unit rate calculations (divide one quantity by another to get “per one unit”) and that combined rates are added. See What is a Unit Rate? Definition, Examples and Gauss Contest Practice.
This review should feel comfortable, not challenging. If your child is struggling with any of these during the review, note it as a topic for post-contest work rather than trying to fix it now.
The evening before the contest
Do no mathematics the evening before. This is not a sacrifice — the marginal gain from one more evening of practice is negligible, and the cost of arriving at the contest tired and anxious is significant.
Instead, confirm the practical details: what time does the contest start, where is it being held in the school, does your child have several sharpened pencils and an eraser? Calculators are not permitted on the Gauss math competition.
Get a full night of sleep. This is not generic advice — cognitive performance on problems requiring multi-step reasoning, which is exactly what the Gauss tests, is meaningfully affected by sleep quality in ways that one more hour of practice cannot compensate for.
What to do on the day of the Gauss math competition
Before the contest
Eat breakfast. Mathematical reasoning requires sustained concentration and concentration requires fuel. This sounds basic but students who skip breakfast before an early morning contest perform below their capacity.
Arrive at the contest location on time and with the right materials. Bring three or four sharpened pencils and an eraser. Nothing else is required — and calculators, notes, and formula sheets are not permitted.
In the minutes immediately before the contest starts, do not try to mentally review formulas or work through problems in your head. Breathe normally, sit comfortably, and approach the paper as something you have prepared for rather than something you need to conquer. The Gauss math competition is 60 minutes of problems — not a test of who you are.
During the contest — the three-pass strategy
The most effective time management approach for the Gauss math competition is a structured three-pass strategy. For a complete explanation of this strategy, see Gauss Math Contest Practice: A Complete Preparation Guide with Past Paper Strategy. The brief version is:
First pass (approximately 25 to 30 minutes): Work through all 25 questions in order. Answer any question you can solve within two minutes. Circle questions that require more time and move on. Do not spend more than two minutes on any single question during the first pass.
Second pass (approximately 20 to 25 minutes): Return to circled questions. With the easier questions already answered and your momentum up, harder questions sometimes become more approachable. Spend up to four minutes on each circled question. Skip any that still are not yielding progress.
Third pass (remaining time): For any questions still blank, make the best guess you can by eliminating obviously wrong options. Review any answers you felt uncertain about during earlier passes.
Important rules to remember during the contest
There is no negative marking. A wrong answer and a blank answer both score zero — so always attempt every question rather than leaving anything blank. On a five-option multiple choice question, a random guess has a 20% chance of being correct. Eliminating one option raises this to 25%. Eliminating two options raises it to 33%.
The scoring is weighted. Part A questions (1 to 10) are worth 5 points each. Part B questions (11 to 20) are worth 6 points each. Part C questions (21 to 25) are worth 8 points each. Getting all of Part A correct is worth 50 points — the same as getting all of Part C correct. Do not rush through Part A to get to Part C. Careless errors on five-point questions are the most preventable source of mark loss.
Read every question carefully before starting to solve it. Many marks are lost on the Gauss not because a student lacks the mathematical ability to solve a question but because they misread what was being asked. Underline the specific quantity the question asks for before beginning any calculation.
Show working on a separate sheet even though only the answer is marked. Working clearly through a problem catches arithmetic errors before you commit to an answer. Students who work in their head make significantly more errors than students who write each step.
Specific topics to watch for in the Gauss math competition
Based on patterns across recent Gauss past papers, these are the topic areas most likely to appear across the three parts of the 2026 competition. This is not a prediction — it is a reminder of what consistently appears so students can look for familiar problem types rather than being surprised.
Part A (questions 1 to 10) — what typically appears
Basic arithmetic with fractions, decimals, and percentages. One or two straightforward geometry questions involving area or perimeter of standard shapes. A simple pattern or sequence question. A basic probability or counting question. One number theory question involving factors, multiples, or divisibility. At least one question based on a table or graph requiring careful reading.
These should all be approachable for a prepared student. The key is not to rush — careless errors on Part A are the main source of preventable mark loss.
Part B (questions 11 to 20) — what typically appears
Multi-step percentage or fraction problems. Algebra word problems requiring setting up an equation from a context. Geometry problems involving composite shapes, angles in diagrams, or properties of triangles. Counting or probability problems requiring the multiplication principle or the complement. Pattern and sequence problems asking for the nth term or a specific term far into the sequence. At least one rate or unit rate problem.
Part B requires more sustained thinking than Part A. If a question is not yielding progress within two minutes, move on and return in the second pass.
Part C (questions 21 to 25) — what typically appears
Multi-step problems combining two or more topic areas. Problems where the approach is not immediately obvious and requires creative mathematical thinking. Geometry problems involving less standard shapes or configurations. Number theory problems requiring deeper reasoning about factors, primes, or divisibility. Percentage trap problems where the intuitive answer is wrong.
It is entirely normal and expected to find Part C questions very difficult. Scoring zero on Part C and near-perfectly on Parts A and B is still a result that earns a Certificate of Distinction. Do not let difficult Part C questions affect your approach to the rest of the paper.
After your child has sat the Gauss math competition
Immediately after — what to say and what not to say
The instinct many parents have immediately after any exam is to ask how it went. This is understandable but worth handling carefully with the Gauss math competition.
Asking how it went is fine. Asking how many questions they think they got right, whether they think they did better than their friends, or what their score might be creates unnecessary anxiety before results are even available and before the student has had time to decompress.
The most useful thing a parent can do immediately after the contest is acknowledge the effort rather than the outcome. A student who prepared seriously and sat the Gauss math competition has done something genuinely valuable regardless of the result — the preparation process itself develops mathematical reasoning that no school class replicates.
In the days after — review the paper
Once the official solutions are published by the CEMC — typically a few weeks after the competition window closes — going through the paper question by question is one of the most valuable things a student can do. This is true whether the result was strong or disappointing.
For every question answered incorrectly, the goal is not to feel bad about the error but to understand exactly what went wrong. Was it a topic gap — the concept required was not known? Was it a reasoning error — the concept was known but applied incorrectly? Was it a time pressure error — the approach was right but the student ran out of time before finishing? Each of these has a different implication for future preparation.
Students who do this review honestly and systematically after their first Gauss almost always perform significantly better in their second year, because the review gives them a precise and personal preparation roadmap.
Results — what to expect and when
Results are distributed to schools in the weeks following the competition window. Your school receives a results package showing individual scores and how students performed relative to the full cohort of participants nationally.
Students who perform in approximately the top 25% receive a Certificate of Distinction. Students in approximately the top 10% receive higher recognition. Perfect scores and near-perfect scores receive special recognition from the CEMC.
The CEMC also publishes score distribution data showing how the cohort performed overall. This context matters — a score that feels low in isolation may be well above average when seen relative to the distribution for that year’s paper.
What comes after the Gauss math competition
For students in Grade 7 sitting the Gauss math competition this year, the natural next step is preparation for the Grade 8 Gauss next year, and then the Pascal contest in Grade 9. The competition pathway builds consistently from here through the CEMC series toward the Euclid contest in Grade 12, where a strong result carries direct weight in University of Waterloo admissions and scholarship decisions.
For students in Grade 8 sitting the Gauss this year, the next competition in the CEMC series is the Pascal in Grade 9. Pascal builds directly on Gauss foundations and adds more advanced algebra, coordinate geometry, and proportional reasoning. Students who performed strongly in the Gauss are well placed to begin Pascal preparation over the summer.
Many students who compete in the Gauss math competition also participate in the AMC 8, which takes place in January each year. The two competitions develop the same underlying mathematical reasoning skills and preparation for one directly benefits performance in the other.

Think Academy Canada and the Gauss math competition
Think Academy Canada is a registered test centre for the AMC series and offers structured preparation courses for the Gauss math competition and the full CEMC contest pathway.
Think Academy’s competition preparation curriculum uses a spiral advancement model — revisiting key concepts at increasing depth across the course rather than covering each topic once and moving on. Live interactive classes, teacher-marked homework, and access to session replays give students a structured and supported preparation experience that is significantly more efficient than self-study alone.
Students who come through Think Academy’s competition pathway go on to sit Pascal, Cayley, Fermat, and Euclid with stronger mathematical foundations than students who prepare independently — not because the content covered is different, but because the structured approach to building problem-solving intuition over time produces qualitatively different mathematical reasoning.
Frequently Asked Questions
When does the Gauss math competition take place in 2026? The Gauss math competition 2026 runs from Monday 11 May to Friday 22 May 2026. Schools administer the contest during this window, so the specific day your child sits it depends on when their school has scheduled it within this period.
What should my child do the night before the Gauss math competition? Do not attempt new mathematics the evening before. A light review of benchmark fractions, key geometry formulas, and angle facts (20 to 30 minutes maximum) is useful. Confirm the practical logistics — time, location, pencils. Get a full night of sleep. Cognitive performance on multi-step reasoning problems is meaningfully affected by sleep quality.
How long is the Gauss math competition? The Gauss math competition is 60 minutes for 25 questions. Questions are weighted — Part A (1 to 10) is worth 5 points each, Part B (11 to 20) is worth 6 points each, and Part C (21 to 25) is worth 8 points each. The maximum score is 150.
Is there negative marking on the Gauss math competition? No. Wrong answers and blank answers both score zero. Students should always attempt every question rather than leaving anything blank. A random guess on a five-option question has a 20% chance of being correct.
What is a good score on the Gauss math competition? Students in approximately the top 25% earn a Certificate of Distinction. The specific score threshold varies each year based on how the cohort performs. The CEMC publishes score distributions after results are released. In general, a score above 100 out of 150 is a strong result.
What happens after the Gauss math competition? Results are distributed to schools in the weeks after the competition window closes. The CEMC publishes official solutions typically within a few weeks. Students in Grade 7 who perform well may consider the Grade 8 Gauss next year and Pascal in Grade 9. Students in Grade 8 are naturally progressing to Pascal. Both grades can also consider the AMC 8 in January as a complementary competition.
How is the Gauss math competition different from the Gauss math contest? They are the same thing. Gauss math competition and Gauss math contest are both names used for the same CEMC event — the 25-question multiple choice competition for Grade 7 and Grade 8 students held in May each year. The CEMC formally calls it a contest rather than a competition but both terms are used widely by students, parents, and schools.
