Stage 9 is for learners at an upper-intermediate level. There are a large number of new words and expressions for students to practise, as well as focused consolidation work on both spelling and pronunciation. As learners are already able to express themselves fairly well, the questions in Stage 9 can be quite challenging. Grammatical work is mainly focused on forms and structures that enable communication to become more natural and efficient. This stage is appropriate for learners at B2 level according to the CEFR.
