Help Make Brilliant Even Better!

You may have noticed that we've launched wiki pages in our practice section. We've got over 100 pages already up and running but we need your help to make these pages a resource that will make an even better place to improve at math, science, and problem solving.

If you'd like to try your hand at explaining a challenging/interesting concept to tens of thousands of other people all around the world, read on!

Our wiki pages are meant to help people who have forgotten (or have never learned) about a particular skill or technique. Our best pages will have:

  • a brief and understandable summary of the idea/technique
  • additional explanation, if it would be helpful or provide added depth
  • some worked examples so readers can see the idea in action

However, any contributions you can make are welcome, as we want to work as a community to improve this resource over time. Here are a couple of examples of some more-developed pages:

So, if you'd like to help, here are some pages that could use your contributions:

Of course, feel free to look around and contribute anywhere else you'd like as well!
