OK, so it's not really called that! Anybody with an undergraduate background in maths or statistics and with a bit of time spare might be interested in this: https://uppsala.instructure.com/courses/28112/assignments/syllabus Delivered completely online and free for all EU citizens (according to David Sumpter on twitter we still just about count!). It's borderline relevant for other things I'm going to be studying next year so I'll probably give it a go as part of my effort to refresh my maths - just wondered if it would be relevant to anyone else's interests.
