Each section opens with a lively presentation page which introduces the point of grammar.

Grammar explanations are short, clear and easy to remember. Colour is used to highlight grammatical contrasts. Each grammar explanation is followed immediately by an activity, so that students can practise before moving on to the next explanation. Engaging practice activities include Internet exercises which enable students to see how language is used in real life, Do-it-yourself exercises encourage students to discover how grammar works, and personalisation activities allow students to use the grammar to talk about themselves.

OEGC Advanced has a special 'Grammar beyond the sentence' section, focusing on grammar for skills and text-structuring.

Interactive e-books allow students to do all the exercises on a tablet or computer, both online and offline. Recordings of texts provide added listening practice. 'Pronunciation for Grammar' has over 100 interactive exercises which help students to understand natural speech, and to improve rhythm, stress and intonation. Record and playback function allows students to listen, think, repeat and record.

A lesson-by-lesson Teacher's Guide supplements the Student's Book exercises with hundreds of additional communicative and out-of-class practice activities, to help students make the move from practising grammar to using grammar. They also contain helpful Language Notes showing typical problems students may have with certain structures, often because of cross-language differences. You can see a sample of the Basic Teacher's Guide, or download the complete Guides free from www.oup.com/elt/oegcteachersguides.

Towards the end of the Advanced level students will be at a level where they will benefit from using Practical English Usage and Practical English Usage Diagnostic Tests.
