Each unit is based on a bite-sized 10-minute episode, and uses spoken language to demonstrate aspects of English usage such as grammar, vocabulary and pronunciation. All key skill areas are addressed, including Listening, Reading, Writing and Speaking. The episodes are independent of each other and can be worked through in any order.

The episodes draw from a wide range of themes: environment, technology, tourism, medicine, architecture, business and commerce, finance, law, and the sciences - archaeology, psychology, biology and chemistry. A variety of activities are introduced in the video segments. These activities focus on developing both the spoken and written forms of the language, improving grammatical accuracy and listening skills, expressing ideas, building vocabulary and other aspects of academic English.
