I think it would be nice if every course had a list of resources pertaining to that specific course. The “resources” document could have things such as links, solutions to common problems, and helpful tips. There could also be a line at the top of the document that indicates when the resources were last verified/updated. If there are no resources for a particular class/course then a document that says “No Additional Resources” or something similar would be nice.
I think that would help a lot of people who are new to some of these topics. This would also help keep the courses a little more up to date and not require a course to be re-recorded. Several times a reference to other resources is made but there are none to be found or they have changed. I found one or two instances where the information is not completely accurate or certain links have been updated.
