AoPS Holidays

There are no classes May 25 ‐ 27, July 4, August 30 ‐ September 2, and November 25 ‐ December 1.

Who Should Take?

Students are ready for this class if they have mastered square roots and fractional exponents, order of operations, linear equations and inequalities, ratio, and proportion. We recommend that students have experience with factoring quadratics prior to taking this course.

Please note: Our Algebra sequence will likely not match up exactly with your school's. Most students who have completed our Introduction to Algebra A course or a high-level honors Algebra 1 course in school are ready for this class. However, we encourage students to take our Introduction to Counting and Probability class before beginning this course. Visit our Recommendations page for help in choosing the right class.

I cannot express how thankful I am for this course. I LOVED it! I had so much fun, and I always looked forward to Fridays to have class. The homework was challenging, but that is when it's the most fun! The instructor was a great teacher who kept me engaged in class, and we did cool problems in class. I learned so much, and I just thoroughly enjoyed this class. Thanks again!
