Brilliant

Brilliant is an amazing concept and I can't wait until someone brings something similar to the blockchain.

The team has created courses and puzzles based in Science and Math, it's an incredible learning tool because it's interactive and they have a community that continually tries to help everyone solve problems.

They have free membership where you can sit down and solve problems, or you can pay monthly membership to go through their courses.

This is an incredible resource, and, honestly, a great use of your time.
