We’re just going to say it like it is: ** Art of Problem Solving** is a math curriculum designed for kids who LOVE math and are really, really good at it. We’re talking about the kiddos who may be starting Algebra 1 at the age of 10.

That’s not to say that other students would not benefit from **AoPS**. But, if your teen enjoys math textbooks with the visual appeal of lots of bright pictures and sideboxes filled full of random fun facts and real world applications of math skills, then **AoPS **will probably not be a good fit.

**AoPS **textbooks are highly regarded for their rigor and depth, but they are dense and intense – which is not a bad thing, if you love math. Written in a conversational style, it’s like reading the transcript from a math lecture. Concepts are introduced and sample problems are explained step-by-step in text and number format.

Students then get the chance to try problems on their own: Exercise problems, review problems, and challenge problems. Don’t worry, though. The Solutions Manual not only gives you the answer, but it also gives you explanations on how to solve the harder problems.

Not sure what level you should start with? Visit the AoPS website’s Recommendation page and look for the Are You Ready? link to find a placement test for each textbook in the series.

Also, be sure to check out the Free Alcumus site on AoPS. You’ll find thousands of problems to supplement some of the textbooks. And, you can even watch video lessons that go with the Introduction to Counting & Probability book.
