Online Competition Mathematics
Build the reasoning, proof, modeling, and problem-solving skills needed for AMC 8, AMC 10, AIME, MathCounts, CMO-related training, and other international mathematics competitions.
A clear starting point
An online math olympiad tutor provides live, structured instruction for students preparing for challenging mathematics competitions. The work goes beyond memorizing formulas: students learn how to recognize patterns, choose an approach, model a problem, write or follow a proof, and explain why a solution works. ACE Academy combines placement testing, small-group English instruction, selected competition problems, homework support, review, and assessment for students ages 3–15.
For families comparing options, our online math olympiad tutoring approach is designed to connect school mathematics with competition-level reasoning. I find that distinction important because a student can know the standard procedure and still need practice deciding which idea unlocks an unfamiliar problem.
Built for serious learners
The strongest preparation is not a pile of disconnected worksheets. It is a repeatable cycle in which students encounter a concept, attempt a problem, receive strategy feedback, revisit mistakes, and then demonstrate what they can do independently.
Classes typically include 6–12 students and run for 90 minutes once a week. Live discussion gives students opportunities to explain an idea, compare strategies, and learn from a carefully selected set of problems rather than only watching a solution.
The course cycle includes preview, live instruction, practice, homework, teacher support, review, and assessment. Students also receive supplementary resources, recorded homework explanations, competition-style practice tests, and learning reports according to the course structure.
Geometry preparation covers congruence, similarity, circles, tangent lines, area ratios, coordinate geometry, solid geometry, trigonometry, and formal proofs. Geometry is especially useful for connecting visual intuition with precise mathematical language and multi-step reasoning.
Students practice mathematical modeling, number theory, counting, probability, algebraic systems, and non-routine problem solving. The goal is not merely to finish one question, but to understand when a strategy applies and how to adapt it to a new question.
Families exploring math competition classes online can use the placement process to identify an appropriate starting point. That matters for both advanced learners and students who have strong school grades but have not yet worked with contest-style questions.
Outcomes that matter
Prepare through AMC 8, AMC 10, AIME, MathCounts, CMO-related, and other international competition content.
Use heuristic instruction, selected problems, and teacher feedback instead of relying on rote memorization.
Connect congruence, similarity, circles, trigonometry, spatial reasoning, coordinates, and proof.
Prepare for school placement tests, Honors or AP mathematics, stronger GPA performance, and STEM study.
See which approach to use, why it works, and how to improve an incomplete or inefficient solution.
Use placement reports, homework review, assessments, and individualized learning recommendations to guide next steps.
A practical starting process
The process is designed to place students thoughtfully before instruction begins and then give them repeated opportunities to practice, revise, and demonstrate mathematical thinking.
New students complete a placement test before enrollment so the recommendation reflects current knowledge and competition goals.
What you see: a level recommendation and learning direction.
Students attend a 90-minute English-language lesson in a small online group and work through concepts and competition problems.
What you see: guided reasoning, questions, examples, and discussion.
Homework, explanations, review, practice tests, and assessments reinforce the ideas introduced during class.
What you see: feedback, progress evidence, and next recommendations.
Curriculum depth
Students who want to compare advanced online math programs should look closely at the curriculum sequence, teacher feedback, placement process, and how much guided practice is included between lessons.
A worked use case
A student preparing for geometry-heavy competition questions may know the area formulas but still hesitate when a problem combines circles, sectors, and triangles. The tutoring process makes the structure visible: identify the relevant sector, calculate the triangle, compare the regions, and explain why the subtraction produces the shaded area.
In the provided example, two circles pass through each other’s centers and the given distance is AB = 6. The solution identifies a sector area of 12π and a triangle area of 9√3. One circular segment is therefore 12π − 9√3, and doubling the two congruent segments gives a common shaded area of 24π − 18√3.
The transferable skill is strategy selection.
The student is not only learning an answer. They are learning how a diagram can be decomposed into familiar objects, how exact values should be preserved, and how a geometric argument can be communicated step by step.
This is the kind of practice found in geometry competition preparation, where visual intuition must eventually become precise reasoning.

Common questions
An online math olympiad tutor provides live instruction focused on advanced mathematical reasoning and competition problem solving. The work may include geometry, number theory, counting, probability, algebraic modeling, proof, and strategy selection. The goal is to help students understand how to approach unfamiliar problems rather than only repeat standard school procedures. In this program, instruction and course materials are delivered in English. Students also receive structured practice, homework, teacher support, review, and assessment as part of the learning cycle.
The program is designed for students ages 3–15 who need competition preparation, advanced enrichment, or stronger school and placement-test performance. It can support students preparing for AMC 8, AMC 10, AIME, MathCounts, CMO-related training, and other international mathematics competitions. It also fits students seeking Honors or AP mathematics pathways and learners interested in STEM fields such as engineering, computer science, physics, or other physical sciences. Because new students complete placement testing before enrollment, families can receive a recommendation based on the student’s current knowledge. The program may also suit students who want to combine school progress with deeper non-routine problem solving.
New students must complete placement testing before enrollment. The listed Geometry placement test contains 16 questions and has a 40-minute time limit, with a passing threshold of 60%, generally 10–11 correct answers. Its content draws from Pre-Algebra A/B and Algebra I A. The AMC 8 Basics placement test also contains 16 questions, takes 40 minutes, and uses content from Pre-Algebra A/B and Algebra I A/B. The knowledge areas include geometry, equations and inequalities, analytic geometry, number theory, square roots, exponents, ratios, rates, unit conversion, percentages, counting, and probability.
The competition curriculum includes geometry, pre-algebra foundations, and Algebra I foundations. Geometry topics include congruent and similar triangles, right triangles, bisectors, quadrilaterals, sectors, circular segments, tangent lines, solid geometry, analytic geometry, trigonometry, and formal proofs. Pre-algebra foundations include advanced arithmetic, prime factorization, ratios, percentages, equations, geometry, counting, probability, data analysis, AMC 8 practice, and pattern recognition. Algebra I foundations include variables, linear equations and systems, inequalities, quadratics, functions, graphs, polynomials, complex numbers, sequences, series, modeling, AMC 8, and MathCounts practice. The wider competition focus also includes number theory, logical reasoning, mathematical modeling, and multi-step problem solving.
The online classes are live and typically include 6–12 students. Each class lasts 90 minutes and is held once per week. The standard semester course contains 18 lessons, with homework and supplementary resources provided in English. The learning cycle includes preview, live instruction, practice, homework, teacher support, review, and assessment. Competition-style practice tests are used to recreate authentic contest conditions. Trial-class availability can vary by course, and the provided information notes that a Geometry trial class was expected to launch in Q2 2026.
The provided math pricing examples show a 36-lesson package at $999 and a 72-lesson package at $1,819.
