Be aware of the auto renewal subscription, Brilliant didn't made me aware of the auto renewal and charged me for another year without my consent. Very disapointing and very hard to contact with the support team, if I click to contact the support team it will open a new window with the google webapge. I feel like it's a scam.

A good effort, worth a try, but has some gaps.

I tried this with my 9 year old son (home schooled). To be fair, does not offer sign up as below 13 years old, so was teaching concepts much further beyond my son's level. I found it great as a tool to sit with him and tutor him with, but I could not leave him with it - I seemed to be able to give much clearer explanations, or walk him through solutions much better than they did. Generally speaking, is interesting, but I’m not sure how it fits in to . It does not seem to teach reliably, it is more reliable for practice. It does have courses, so supposedly is for teaching, but it’s focused on applied activities, so it is only when you get it wrong or click “view solution” that it teaches you. That general approach is potentially quite good (e.g. if you get the answer right, it does not waste your time teaching you), but unfortunately the explanations it gives you to teach you were not very kid friendly - it uses a lot of big words and assumes a lot of prior knowledge, which it does not give you links to explore further if you don’t have that knowledge, so it can leave you hanging. Having said all that, it still leaves me with the question: is there a resource like for students under 13 years old?

Is It Any Good?

Brilliant is elegantly laid out and easy to navigate. It lets kids solve problems at their level while getting immediate feedback from other folks who are just as enthusiastic about math and physics. They'll appreciate the choices they get to make -- they get to pick the problems they find interesting. Even better, they can create their own problems to try to stump friends. The site's existing problems are moderately intriguing; they're pretty similar to the types of story problems you find in traditional math and physics textbooks.

A minor quibble: answers submitted don't require the use of units, which could be particularly problematic in physics. Note that this site is aimed toward "exceptional students," so it may not be appropriate for kids who are having difficulty with math or physics. Also, the forum is open to all math lovers over the age of 13, so make sure to talk to your kids about digital citizenship.

Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
