Independent HiMCM information & preparation support
BUILD A MODEL.
DEFEND EVERY CHOICE.
A clear English-language guide to competition rules, team formation, preparation, paper study, and independent coaching support for the High School Mathematical Contest in Modeling.
Rule snapshot based on COMAP’s published 2026 information. Always verify the current official instructions before registering or submitting.
What this site helps you do
FROM OPEN PROBLEM
TO COHERENT PAPER.
Contest guide
Read a plain-English map of eligibility, team structure, registration, submission format, academic integrity, and the official channels that control the rules.
Team matching
Build a team around complementary roles: modeling, computation, research, writing, and quality control. Matching is support, not a guarantee of placement or results.
Preparation plan
Move through problem interpretation, assumptions, model design, sensitivity analysis, validation, visual evidence, and a disciplined writing workflow.
Paper library
Use historical problems and selected learning materials to study structure and reasoning. Do not copy models, prose, figures, code, or citations.
Coaching support
Request independent instruction, milestones, and feedback. Students remain the authors and decision-makers; no award or outcome is promised.
Official sources
Go directly to COMAP for current dates, fees, registration, contest documents, and final submission rules. This site is not COMAP and does not speak for it.
A repeatable modeling loop
THE PAPER IS
A RECORD OF DECISIONS.
Strong work is not merely a complicated equation. It is a traceable argument that connects the question to assumptions, data, a mathematical structure, results, limitations, and practical interpretation. Each revision should make that chain easier for another person to audit.
Frame
Translate the prompt into specific questions, variables, constraints, outputs, and evaluation criteria.
Assume
State what is simplified, why it is reasonable, and how each assumption could affect the result.
Build
Choose the simplest model that can answer the question, then document equations, algorithms, and data treatment.
Test
Use validation, scenarios, sensitivity analysis, boundary checks, and error discussion to challenge the model.
Explain
Make figures, tables, and prose carry the reasoning. A reader should understand what changed and why.
2026 official snapshot
MARK THE
WINDOW.
COMAP currently lists the 2026 HiMCM/MidMCM contest window as November 4–17, 2026. A team may consist of up to four high-school students. The official instructions state that the solution must be written in English and submitted as a PDF of no more than 25 pages, including the summary sheet. Registration and final rules are controlled by COMAP.
Suggested preparation rhythm
TRAIN THE
WHOLE SYSTEM.
Foundations
Review modeling vocabulary, dimensional reasoning, data hygiene, citation practice, and a shared technical stack.
Mini cases
Complete short exercises that isolate problem framing, model selection, computation, visualization, and writing.
Full simulation
Run a timed past problem with role rotation, checkpoints, version control, and a final PDF inspection.
Debrief
Identify bottlenecks and convert them into a concrete checklist for the official contest window.
