Math competitions for high school students?

Hey everyone! I'm super into math, and I was thinking of participating in some math competitions to expand my skills and have fun. Do any of you know about any popular high school math competitions, both on a national and an international level? Please drop your suggestions below!

Hey there! It's awesome that you're passionate about math and looking to challenge yourself through competitions. There are several well-known math competitions for high school students at both the national and international levels. Here are some to consider:

1. American Mathematics Competitions (AMC): The AMC consists of three levels: AMC 8 for middle schoolers, AMC 10 for grade 10 and below, and AMC 12 for grade 12 and below. These competitions are held annually by the Mathematical Association of America (MAA). High-performing students in the AMC 10/12 series might later advance to the American Invitational Mathematics Examination (AIME) and eventually the USA Mathematical Olympiad (USAMO).

2. MathCounts: This competition is aimed at middle schoolers, but if you're involved in math coaching or tutoring, you can help mentor younger students participating in this competition. MathCounts involves both individual and team rounds and focuses on problem-solving skills.

3. Math Olympiads for Elementary and Middle Schools (MOEMS): Similar to MathCounts, MOEMS targets students in grades 4-8, but it is worth mentioning because high school students often serve as team coaches or tutors.

4. Harvard-MIT Mathematics Tournament (HMMT): This is an annual math competition held jointly by Harvard and MIT, featuring both individual and team events for high school students. It is widely considered to be one of the most challenging math competitions and attracts participants from around the world.

5. International Mathematics Olympiad (IMO): Held annually, the IMO is the most prestigious and well-known international math competition for high school students. To participate, you'll need to represent your country as part of a national team, which typically requires performing well in a series of national qualifying examinations or competitions.

These are just a few examples of popular math competitions, but there are many others out there. You can also explore regional and state-level competitions organized by local math associations or universities. Good luck, and have fun testing your skills!
