OpenLearn — free short courses and learning resources from The Open University

The Open University's OpenLearn platform provides hundreds of free short courses, articles and multimedia learning resources across many subjects, from languages to finance and STEM. Resources are open to anyone in the UK (and worldwide) with no formal entry requirements; you can study online at your own pace and download materials or register for a free account to track progress. Some courses offer optional statements of participation for a small fee, but the core learning content is free.
