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.

Can't cancel 7-day trial (solved) Tried to cancel the trial before deadline, but the cancel subscription button won't work (still doesn't work now). No way to cancel, I got billed €124,95. Immediately requested for a refund and haven't used any courses since being charged, will update if I receive it. Be careful with this company. UPDATE: Thanks you Steph from customer service, who has promptly issued a full refund after an email. It may be better to directly email the support team rather than to submit a refund request through the app. The app itself is good to awaken a beginner's interest, but offers not much after that. If you want to cancel a trial, make sure to do so through email to be safe.

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.

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

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!
