We do not always have permission to share all course material with the general public.
Our professors often reference slides and notes during their lectures for the students. This is because most of our courses are portions of classes offered on campus for graduate student credit. The resources the professors mention are specifically connected with those credited courses. Unfortunately, this means that not all of those resources can be made available for the free online courses.
We are always working to add more value to our courses! If those notes or slides become available, rest assured that we will alert everyone who has ever taken that course that the new resources are now available.
