I have undergraduate level experience in macroeconomics...but I want to do some further learning to try and acquaint myself with where mainstream macroeconomics is at the moment in the hopes that I can understand the economy better. I understand that most macroeconomics is highly mathematical at this stage and I have no problem with this, but a more intuitive/wordy/theoretical approach would be preferred.
Are there any good online lecture notes, textbooks etc. for this sort of thing?
