Introduction
The best way to prepare for math contests is to do lots of practice problems and learn the material necessary to solve the problems. There are also many books and online handouts/lectures you can use to improve your problem-solving skills. Depending on your current abilities, you will want to start out with different practice problems, different books,
Books
The Art of Problem Solving books are an excellent resource to help prepare for math contests. They cover a broad range of topics, from algebra to geometry to number theory to combinatorics and much much more.
- Art of Problem Solving Volume 1 - Mathcounts, AMC 8, AMC 10
- Art of Problem Solving Volume 2 - AMC 12, AIME, USAMO, MOP
The AoPS textbooks break down specific areas of mathematics. These books are on 3 levels, Introductory, Intermediate, and Advanced. The Advanced series, as well as part of the Intermediate series, has not yet been published. These books are indexed here. Excerpts are provided, as well as pretests and posttests to see if the books are on the right level for you. Alcumus is a good resource even if you do not own any of the AoPS books.
- Prealgebra - Mathcounts, MOEMS
- Introduction to Algebra - Mathcounts, AMC 8
- Introduction to Number Theory - Mathcounts, AMC 8, AMC 10, AMC 12, AIME

Practice Problems
Old practice problems (with solutions) sorted by contest and year are available on the Wiki and the Resources section. Many practice problems are also available on the forums.
Here are some old contest archives that may be useful for practicing with:
American Mathematics Competitions:
- AMC 8 Problems and Solutions - AMC 8 is a national contest for grades 8 and younger.
- AMC 10 Problems and Solutions - AMC 10 is a national contest for grades 10 and younger.
- AMC 12 Problems and Solutions - AMC 12 is a national contest for grades 12 and younger.
American Invitational Mathematical Examination:
- AIME Problems and Solutions - AIME is a contest administered to those who qualify with a high score on the AMC 10/12.
United States of America Mathematical Olympiad:
- USAMO Problems and Solutions - USAMO is a proof-based contest which must be qualified for through a combination of AMC & AIME scores.
Harvard-MIT Mathematics Tournament:
- HMMT is a nice contest on a hard AIME level.
There are certain strategies in preparing for the AMC 10/12- especially qualification for the AIME.
The AIME cutoff has ranged 84-95 on AMC 12.since 2020 when the qualification was loosened to "5% of scorers". In order to get a score in the range, a simple way is to answer 13 questions right (check your work carefully!) and leave the rest blank, which earns a score of 96. In the past, since the 2020 cutoffs have beenontests have been getting slightly harder each year, and new generations of competitors don't always match the new level. This means, since the first 10 questions are solvable in half the test time by most people who prepare, they are 60 easy points. Throughout questions #10-#20, answering 3-5 shall be enough to qualify.
Beware, though, that the AIME question #1 is harder than AMC question #10, so this strategy presumes that you *could* solve more than 15 AMC problems, but you are choosing to reduce your time/difficulty pressure and increase your confidence, to guarantee a qualifying score but not get your highest possible score.
Qualification for the USAMO, however, is much harder. Only 260-270 people qualify every year. USAMO qualifiers need a good combination of AMC & AIME scores. The average score on the AMC 12 for a USAMO qualifier is around 114-132. There are simple ways to do this but it takes a lot of work. Answering the first 15 right, and then getting 5 out of the 10 left would usually qualify.
The AIME cutoff on the AMC 10 have ranged throughout (96-104) in recent years. The top 2.5% of scorers qualify. The AMC 10 does test less topics than the AMC 12 but many questions go into much more depth. Cutoffs on the AMC 10 are higher since the testing only tests topics up to Geometry. AIME ranges from Algebra to precalculus, which means only very elite scorers make it. Though the qualifying scores are high, there is indeed a good strategy. Since you get 1.5 points for each question blank, it’s good just to do what you know. Answering 15 questions right and leaving the rest blank would earn a score of 105 while answering 20 right and leaving the rest blank would earn a score of 127.5. Since contests are getting harder as said earlier, 15-18 right should be enough.
Qualifications for the USAJMO is similar to that for the USAMO except they use AMC 10 scores.
Top 10 most Difficult math Competitions(National) in The USA:
10. MATHCOUNTS - Pre-Algebra, Geometry, Number Theory, Combinatorics, Logic
9. AMC 10 - Intermediate Algebra, Geometry, Advanced Number Theory, Combinatorics
8. AMC 12 - Intermediate Algebra, Geometry, Number Theory, Combinatorics, Pre-Calculus
7. ARML - Advanced Algebra, Geometry, Number Theory, Combinatorics
6. AIME - Advanced Algebra, Advanced Geometry, Number Theory, Combinatorics, Pre-Calculus
5. USAMTS - Advanced Algebra, Advanced Geometry, Number Theory, Combinatorics, Pre-Calculus
4. USAJMO - Advanced Algebra, Advanced Geometry, Advanced Number Theory, Combinatorics
3. USAMO - Advanced Algebra, Very Advanced Geometry, Advanced Number Theory, Combinatorics, Advanced Pre-Calculus
2. IMO - Very Advanced Algebra, Very Advanced Geometry, Very Advanced Number Theory, Advanced Combinatorics, Advanced Pre-Calculus
1. PUTNAM - Advanced Algebra, Geometry, Number Theory, Advanced Combinatorics, *Extremely Advanced Calculus*
Forums
The forums are one of the best ways to find problems to solve, get help with problems you cannot solve, and collaborate with people of all levels and abilities. The forum is divided into many subforums for problems of different difficulties.
- The Middle School forum is for MathCounts and AMC 8/10-level problems.
- The High School forum is a good place to find AMC10/12-level and AIME-level problems.
- The Olympiad forum is a forum for problems at the olympiad level.
- The LaTeX and Asymptote forum is a place to get help with , which is what you use to type things like on the forums. It's also for Asymptote, which is what we use to make diagrams, like:
