Opportunity BasketMath Olympiad Problem Curation Service + Weekly Problem Sets
A curated, hand-selected weekly problem set service delivered via email and a simple web portal. Each week, a team of competition math coaches selects 3–5 original or lightly-adapted problems from number theory, combinatorics, and algebra, paired with detailed solution sketches and pedagogical notes explaining the key insight. Problems are sequenced by difficulty across a semester, with explicit prerequisites called out (e.g., 'requires Fermat's Little Theorem').

Value Proposition
Eliminates the 8–15 hours per month teachers/students spend hunting, vetting, and organizing problems across Reddit, AoPS, and old competition archives. Guarantees pedagogically-sound sequencing and deep solution commentary that textbooks and problem banks lack. Direct relationship with problem curators means students can ask clarification questions on specific problems.
Target Audience
Self-directed high school students (grades 9–12) competing in AMC/AIME/IMO prep; math teachers building enrichment curricula; homeschooling families.
Key Features
- Weekly themed problem sets (e.g., 'Modular Arithmetic Tricks', 'Pigeonhole Principle Applications') with 3–5 problems each
- Difficulty rating (1–10) and estimated solve time for each problem
- Solution sketch + 'key insight' summary (not full solution, to preserve struggle)
- And more, with full implementation detail...

High school students lack access to challenging, self-directed math problems that develop competition-level problem-solving skillsHigh school students interested in mathematics struggle to find curated, appropriately-difficult number theory problems that bridge the gap between standard curriculum and competition mathematics. Teachers and self-directed learners lack a centralized resource for discovering problems that build deep mathematical thinking, forcing them to piece together solutions from scattered sources or abandon independent study.
