Good customer service! Good customer service! I've stopt using brilliant, but forgot cancel substription, so next subsription got payed automaticly. I've didn't want to use brilliant this year so i contacted to customer service. And got contacted to Steph. I got helped quickly, and kindly. Its nice to meet company which is not made just for taking people money. Big thanks to Steph!

Just brilliant The app is amazing. The courses are well made and i love the streak notification that keeps me engaged. Well worth the money and a good app for anyone, either you need to fresh up your knowledge or for learnig new skills. Customer service is amazing as well , quick replies and so focused on helping and taking care of their customers. Thats what a professional business looks like. I have absolutely nothing negative to say about Brilliant. I warmly recommend it.

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.

Refund request Excellent response from Customer Service to my refund request which was processed in a quick and friendly way.

Interactive activities I enjoy the interactive activities. They help make the learning process tangible. Their support team is great, too.
