Our experience over the last five months with AoPS's Prealgebra course has been transformational! Our kids used to dread math—but now they're discussing math together while we’re hiking, having dinner, or visiting with family. Wow! Jean R. Boing Boing

AoPS courses are a wonderful balance of challenge and guidance, constantly stretching students and inviting them to wrestle with problems at their own pace until they reach epiphanies. Bravo! I wish AoPS had been around when I was in high school. AoPS Online Parent

My son is eating your classes up. He is pumped for each Wednesday and has to really work to solve the problems. He's always loved math, but cannot get enough of it now. Way to provide the best educational product this Dad has found anywhere! John C.

I'm impressed at how much my son loved Precalculus. Sometimes he spent two days on his written proofs! I love that students weren't treated with kid gloves but instead afforded respect as burgeoning mathematicians. Now he's looking forward to Calculus. My daughter was already very good at math before she took Prealgebra through AoPS. Since then, she's become an even stronger and more confident problem solver while progressing through the curriculum. Russell

We were incredibly lucky to have three passionate instructors in ChemWOOT who were able to capture the beauty and diversity of chemistry. This class was like a reaction chamber of some of the most motivated chemistry students in the country. The experience was really powerful. AoPS Online Student

I've definitely developed a lot more confidence in math since taking AoPS Introduction to Geometry. In the process of doing harder problems than I ever knew I could, I've also begun to see geometry as an art. I'm enjoying math more and more! AoPS Online Student

Great course! I'm a senior in high school and I decided to take Intermediate Counting & Probability because I'd never been exposed to problem-solving math before, let alone discrete math. Now, I feel ready to take the 400-level combinatorics sequence at college in a few months, and my problem-solving skills have improved a lot. AoPS Online Student

Where I live, calculus is not offered in high school, so I've really treasured my AoPS Calculus class and everything I've learned. Thank you again for this incredible opportunity! Jorge Castello

My instructor was great. I really enjoyed having a woman instructor as a role model and just an all-around-great mathematician! She was always willing to offer advice and knew just how many hints to give to keep problems doable but still satisfying. AoPS Online Student

Every class I've taken with AoPS has been fantastic. Everyone does a great job helping students succeed while enjoying the process of learning math. I love that the students themselves are always open to helping each other out. Matthew
