Is there a way for me to copy the units in its entirety for my students who does not have access to the internet?

Hi Trennecia,

As of now, Khan Academy does not have PDF files of the content to download for students. However, as listed in this article, your students can download content on the apps for offline use, or Kolibri to watch Khan Academy videos and complete exercises without an internet connection.

I hope this helps! Please let me know if you have any further questions!
