The British Council
The British Council website contains a plethora of free resources to assist English language learners in improving their English skills. A Royal Charter governs the British Council. It is also a public corporation and a non-departmental public body (NDPB) supported by the Foreign, Commonwealth, and Development Office. The company's headquarters are in Stratford, London. Stevie Spring is its chairman, while Scott McDonald is its CEO. While the website's study material is nearly entirely in British English, the extensive exercises and detailed explanations are beneficial to both British and American English students. The British Council contains a lot of valuable material about listening examinations, such as recommendations for preparing for your English listening exam and thorough listening exercises.
The listening activities are divided into five categories: A1 and A2 (for beginners), B1 and B2 (for intermediates), and C1 (for advanced). In addition, each exercise includes a worksheet to complete after each activity, as well as an answer key and audio transcript to assist you in checking your answers. While the exercises on the British Council website aren't specifically developed for an exam, they are precise enough to help you refine your listening skills as you prepare for test day.
