I found a mistake in the curriculum!

Just like anyone, we make mistakes too, sometimes. If you find an error in our materials, please check our corrections page to see if it's been added.  If not, please let us know with as much detail as possible.  This will allow us to go in and make changes to the curriculum as efficiently as possible.  However, do make sure you are using the latest versions of the PDFs as we do update these from time to time.
