Kind of a cool system Kind of a cool system. I did not stick with it cause life is too busy. When they charged me and I cancelled just after they were flexible about giving a refund. They only do that once so don't be sneaky!!

A great app for learning A great app for learning. Sadly though, I didn't have time to use it and had to cancel my subscription only to realize that the said subscription already started. However, with their great support, they were able to help me sort it out with a refund. Nothing but great experience so far. I highly 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.

Customer Support Just want to say that in these days of AI/Automation, it was extremely pleasant to get real, prompt and excellent customer support. Maria responded right away and took care of the matter right away! Awesome!

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!
