If you use Google Meet or Zoom or some kind of Desktop recording software, you can record yourself talking between blank or paused video while taking the online course and have the transcript + your own voiced notes with the recording as review material + courseware.

If you take the trouble of revisiting , revising, re-note-taking you might end up with better understanding and even self-generated workbook + answers too ( including your mistakes and what is a false trail or false path and the correct approach ) .
