I am a retired engineer and taking the course to learn something about Macroeconomics and "what makes the world turns." I am on Module-8 now. It is fast pace and very rich course. The content is high density with many technical terms to learn and keep in mind. Abbreviations of these terms add to the complexity of the content. I am learning a lot from the course, much more than I expected. It is not easy but I find it very useful.
Is there a set of notes for the course, references, literature recommended?
