Perfect app and great support team This is indeed great app and great people who support it. I think it is hard these smartphone days and distractions all over to focus and study, although it is so interesting stuff to learn. I wish I had the time and learning skills to use it properly. Last thing to note the subscription model, where you automatically paying w/o noticing should be changed. The company must try to find a way to inform customers before auto renewl period

Such a great way to learn Such a great way to learn! Algebra is like a foreign language to me most of the time. This program helps me decipher and understand the practical application of Algebra. I would 100% recommend Brilliant to anyone in search of a better way to engage with math. Also, their customer service folks are excellent.

Great interactive learning tool Great interactive learning tool, works like duolingo but for maths!

Disappearing classes Although the classes are interesting and the math is (sometimes) well explained, there are also a lot of issues with Brilliant: *Classes disappearing in the middle of doing it. Algebra 2 for example *Classes skimming through essential piece of information, e.g. Introduction to linear Algebra. I'd really recommend a mix of other solutions if you want to further your understanding of mathematics. Khan Academy & 3Brown1Blue (and many other free resources) provide better explanation and have the same level of interactivity.

Excellent learning tool Content is designed simply to increase readability, and attached to examples that help solidify the principles. Very organized and navigating courses and content is smooth. Fair customer service that strives to evaluate needs on an individual level.
