Great Math Resource

I enjoyed my time using the site to explore new ideas to engage myself and my students in secondary and post secondary mathematics education.

Fantastic customer service

Fantastic customer service! I sent an email and, within 20 minutes, received a reply that addressed my issue. No AI, no case #, no link to pages that had nothing to do with my issue. I'm really amazed -- and happy!

Horrible customer service

Horrible customer service. Refunds are impossible besides under some super exceptional circumstance. The courses are also super basic, pick up any elementary book and you will learn much more.

Avoid Brilliant.org - it’s a money driven scam

Like several others who’ve had the misfortune of subscribing to this service, I followed their instructions to the letter when I attempted to cancel their annual membership. So far, they’ve made a total of 11 attempts to bill my credit card even after I cancelled my subscription. This organization cannot be trusted and I see no value in ever doing business with them ever again. My advice - avoid brilliant.org like the plague!! As for my next steps, I’m going to the BBB!

Shady subscriptoin renew

Brilliant.org charged me for annual subscription without notice, and refused a refund. And even canceled our subscription. Support won’t help. Shady behavior. Never buy annual subscription”

Complete scam and waste of money

Complete scam and waste of money. I can for sure do a reclaim on my card. They accept credit cards and there is no way to cancel (emails are conveniently not adhered to). Here's what I would do: contact the bank, show them that I cancelled and ask for a reclamation. Waste of time, and additional effort. That being said, this is an "educational" platforms with pathetic morals - why and what would I trust them to teach? Nope!

Don't touch it.

I had the same experience as other 1 star reviewers here. The free trial is like a trap. If £100 makes a difference to you, don't touch it.

Thank you Brilliant

When first time i saw this app on play store i was shocked. The idea behind it was magnificent. But I doubt that they can make it real, spoiler alert: they did.The topics are Brilliant, and wide. From it to art to mathematics. I'm from Iran. A country in middle eats. Unlike they're politicians Iranian are kind, happy and funny. In January, regim kills around 10000 Iranian protests. They shut down Internet and kill their people. It's a very dark and terrifying era in my whole 5000 years of Iran history. But one thing make me feel better. Brilliant was helping us. They didn't broke our strike chain . Even this little help was alot.Thank you Brilliant. Thank you Steph(the admin)

A Solid Platform, but with Room to Grow

I think Brilliant is decent, but not outstanding.I’ve tried it, and it’s especially strong for mathematics.However, if you want to improve your programming skills (for example in Python), it’s smarter to learn with the help of AI and to experiment using online coding compilers.This way, you can learn for free and at least ten times faster, which simply makes more sense.I also believe Brilliant could benefit from offering more dedicated courses in science and engineering, such as civil engineering, energy systems, chemistry, optics & photonics, and mechanics. Some of these topics are touched on in the Scientific Thinking course, but in my opinion, they deserve full courses of their own.

1/2 star deserved

If I could give 1/2 star that would be awesome. This company is a total rip off. They charged me for something I never purchased. I have no account with Brilliant and they won't refund me unless I sign on to my account. Of course, yet again I do not have an account with Brilliant. Customer service on refunds deserve a ZERO!!!!!!

Really liked the sample but asking for your payment information before the "trial" period seemed like a test of your intelligence in itself.It's too bad because I was pretty likely to have subscribed it it hadn't been for that.
