Oxford University Press is offering 148 e-books free of charge until the end of June. At the time of writing, that means you have almost six weeks to select a graded e-reader to suit your level and interests. Remember, there’s no charge until 30/06/2020.
All you need to set up an account if you do not already have one is an email address. Remember to enjoy a free e-book (or two?!) before the end of June. It’s a great way to develop your English language vocabulary and other skills.
