We understand that you'll want to migrate all your existing materials over to TeacherMade to get the full benefit of auto-graded interactivity. We don't currently have a way to automatically import from other systems like Kami, ClassKick or Nearpod. But if your system can export or save to a PDF file, that will let you easily migrate from the old application to TeacherMade. Just save the PDF, then create a new TeacherMade activity and import the saved file.
