If you have read 20 000+ math contest problems and solutions and enjoyed it, this post is also for you. Although I have included *Mu Alpha Theta* in that list, I have never actually counted (or approximated) the number of questions. This means that the title of that post should have been 30 000 contest problems. Yes, Mu Alpha Theta is one of the richest math problem sources on the net.

**Mu Alpha Theta** is the US National High School and Two-Year College Mathematics Honor Society. It has more than 88,000 student members in more than 1,800 schools. The Mu Alpha Theta competition is held every year and the website has released competition questions for the past 17 years.

The Mu Alpha Theta website contains more than 10,000 math questions from its past tests including solutions and answers. The tests includes questions on Algebra, Geometry, Calculus, Matrices, Number Theory and other fields of mathematics collected from 1995 to 2011. If you want to test your mathematical skills, it looks like you’ll have enough problems to solve for the next couple of years.
