Macroeconomics (Khan Academy)

A gentle route in, and the easiest course here to dip into one topic at a time. Khan Academy's free Macroeconomics course walks through GDP and how national income is measured, inflation and the cost of living, aggregate demand and supply, the monetary system, and the Keynesian cross and IS-LM models that sit behind many arguments over stimulus spending. Each topic is a run of short videos with practice questions, so it works as a quick refresher before a jobs report or an interest rate decision. A companion Microeconomics course covers the other half, and separate AP versions follow the exam framework; for following the news, the general courses are the better fit.
