Learning How to Learn is a COURSERA course, starting in October, which explains the way we store and retrieve information, and gives valuable advice how to study, revise and remember things not just for the exam the following day, but forever. It is very useful for learners of all ages.
Another interesting course from FUTURELEARN is Exploring English: Language and Culture. It is ideal for learners of English as you improve your language skills by watching videos about life in Britain. The course is both enjoyable and informative.
