1. The Open University The Open University offers short, self-study courses for free. There are a wide variety of subjects including the Arts, Business, Science, Technology and much more. You can take a course via the website, or download a DOC/PDF/Kindle/ePub format of the course text (any interactive elements or videos will not be available in the electronic documents). The course listings let you sort the courses by duration. The courses are very amenable to short, bite-size chunks of learning. You can complete one course section at a time rather than finish a course in one go. https://www.open.edu/openlearn/free-courses/full-catalogue https://www.open.edu/openlearn/free-courses/full-catalogue 2. BBC Bitesize Bitesize is the BBC's support resource for school-age pupils in the UK with simple-to-follow lessons and videos. It's actually an excellent learning resource for adults too! The explanations are a model of clear writing without dumbing-down a topic. Any grown-up reading the site can learn a lot about a topic (as well as how to write with clarity and without waffle). Not convinced? Try this random topic and see if you like the explanation (or not!)
