Hi:
I am not sure what you mean by "all the presentations". Most of the classes in the SAS Academy library have transcripts of the narrator's lecture, inside each class. In the Table of Contents for a class, look for a PDF icon that says "Course Notes". If a particular class has the Classroom course notes that we use, you will find a link here. (Just to clarify -- the Course Notes will be the presentation we use in the classroom, which will not correspond exactly to the e-learning videos, but is the closest document with a presentation that we have.)

Here's an example of the Big Data module, where you can see that one class does NOT have course notes and one class does have course notes available.
