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.

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

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.

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!

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!!
