AIME
Take an authentic 15 problem AIME I/II examination, randomly sampled from over 3000 questions sourced from contests held between 1984 and 2025.
The American Invitational Mathematics Examination, a 15-question, 3-hour test. Unguessable. Unforgiving. Designed to probe genuine mastery of combinatorics, geometry, number theory, functional equations, clever transformations, and deep pattern recognition. In AIME 2025, the top 5% scored 11. Rooting for your success!
Take an authentic 15 problem AIME I/II examination, randomly sampled from over 3000 questions sourced from contests held between 1984 and 2025.
Ease into the AIME by sampling from the Easy section aka Problem 1,2,3. Experts can grind the superhard Problems 13,14,15. Test your luck with an AIME Snake & Ladders.
Build your own AIME by hand-picking questions, and assign it to your students with ease.
In-person team mathematics contests held across the United States, such as HMMT, SMT, PUMaC, and the Carmel Math Invitational, are always an excellent opportunity.
Over 660 high-school problem solvers and 119 teams gathered at the recent Harvard/MIT Mathematics Tournament. November problems range from mid-AMC to upper-AIME difficulty, while February ramps up to mid-AIME through olympiad level
Run entirely by Stanford undergrads, the Stanford Math tournament will host ~800 high school contestants this year. Two 50-minute individual exams consisting of 10 short answer questions in Algebra, Calculus, Number Theory, Combinatorics, and Geometry.
Meet the all-star team of Hrishabh Bhowmik, Alex Gao,Arjun Raman and Ekansh Malhotra who created one of the highest quality mocks in recent years, INMC 2025
There are several excellent resources for students preparing for the 25 question 75 minute multiple choice Americal Mathematics Competitions.
The Russian School Of Math offers the entire AMC8 problem set with detailed solutions.
invexic's Problem Trainer filters, sorts and analyzes problems by difficulty, time and category. invexic also provides a detailed breakdown of 2025 AMC10 papers, by level and subject category.
AMC 12 covers the entire high school curriculum including trigonometry, advanced algebra, and advanced geometry.
Ask virtually any IMO medalist or USAMO winner:
The only way to learn mathematics is to do mathematics - Halmos
I like doing things that are fun. If it’s not fun, I stop doing it - JHC
I hate teaching from books. Mathematics is something you do, not something you read - JHC
Play is essential to understanding mathematics - Feynman
If math does not reshape how you think, wonder, and play, it has failed you. Do not become mere Bible salesmen, reciting rules without curiosity. Math must remain a joyful act of exploration, a place where half-formed ideas are welcome. - Perlis
Mathematics is a product of clarity and understanding, not just theorems - William Thurston
A mathematician’s work is mostly a tangle of guesswork, analogy, wishful thinking and frustration - Gian Carlos Rota
Don't just read it. Fight it! - Terence Tao
Math is not a spectator sport - Polya
Advanced mathematics topics are best introduced to young students by motivating the concepts through problems - Titu Andrescu
Mathematicians warn against turning living ideas into dead scripture. Presenting math as a polished cathedral hides the messy, playful process by which it is actually created. Be outspoken against sterile math education. Encourage Experiments. Make Mistakes. TAKE RISKS. Above all else, P L A Y.
threejs experiments present a playful, messy, futuristic view of Math in 2030 & beyond!
