3 stars: On the whole it's quite informative. But the exercises (and the explanations) quickly become frustrating. Figuratively speaking you're too often supposed to be able to accomplish a perfect double flip backwards after doing ten sit-ups. I'm often ranting... which isn't a sign of me having fun or learning anything new. I'm probably just a very dumb person.
5 stars: Nice realised concept, best app in brain teasers. Now become more casual: one daily task with article, the beginner difficulty compared to old concept(there were 3 levels, but only problems). No addictive features (bad ones), so that why model and support will go down, not efficient for market(what makes more unique)
5 stars: I find it fascinating that I don't really know what I know and this app teaches me more about the \
5 stars: It's a nice app. And I heard it presents courses in a simple way for easy understanding. Its definitely something you can try out
5 stars: Very amazing. The application comes with a lots of courses that are brilliant to understand. I used this application, and learning difficult concepts became easy for me. There are no video lectures, as no one has enough time to watch all the lectures. Learning is simple and enjoying with brilliant, I have tested many other education app but no one is good as Brilliant Really, this app worth the cost.
5 stars: I like this kind of approach to learning. Through exercises and explanations. Much easier to understand and remember...
