There is an error in one of your lessons. How can I report this to you?

In this article, we explain how to let us know when you find an error in one of our lessons.

We make every effort to ensure accuracy and consistency throughout our educational materials. However, on occasion errors do find their way into our lessons. If you find something that needs to be corrected, please use the GIVE US FEEDBACK button at the bottom of the slide in question to report it to us. Please give as much detail about the error and how it should be corrected.
