Somehow the world of academia has got a hold on me so even though I graduated last year I'm already looking for opportunities to take classes again. A few months ago I told this to a colleague of mine and she recommended taking a couple summer courses at a university in the Netherlands.
Taking a couple courses in the summer is a great alternative to getting your full degree in Europe or doing a semester abroad through your university which is usually quite expensive. It's also a great option if you will be spending a longer duration visiting a country and would like to make some friends while you're visiting.
Below is a list of universities where you can take a summer course. This list includes universities I've attended, my friends have attended, places I've applied to in the past, and programs I've stumbled across throughout the course of my research.
