Challenging App, Outstanding Customer Service
Took advantage of Brilliant.orgs most recent email discount. I enjoy the challenge of even some of their simplest questions because I have discovered that I have forgotten a lot of the mathematics I learned in high school and in the military. Had one tiny issue with billing, but was treated MOST fairly by Brilliant.org during the short, painless resolution process. Five Stars from me!!!!
