Brilliant App!

Reviewed on 2022-01-04T10:22:32.000Z

This app was a really excellent way to either revisit some old concepts I had forgotten about,or tune up some things that have been difficult for me (*cough*cough* physics). The cancellation service was very easy, and Sandy puts the “support,” and “team,” in “support team.” My only reason for cancelling was to try and save some money with some hospital bills in the background. I hope to rejoin soon!

I found this site to be educational and user friendly. It’s too bad my daughter did not want to continue studying with Brilliant.The subscription cancellation process was simple and Sandy from Brilliant support team was very helpful. Keep up the good work.

Not like my high school math classes

Reviewed on 2021-12-29T16:57:22.000Z

Brilliant.org is not what I expected, but definitely an awesome learning platform.My boss recommended it to me as a way of continuing education. The platform is trying to teach a way of thinking about efficient and effective problem solving, not just memorizing formulas. This is different from my experience learning out of textbooks and school math courses. The problems and exercises require logic and weighing different methods of solving to find what is the best method for that particular problem. The images and stories behind the problems lead me to believe that this would be effective for many different kinds of learners. Although this might not be the best tool for reviewing concepts learned in math class, it is definitely a powerful tool for taking STEM thinking and problem solving to the next level.
