English in Mind is a six-level course for teenagers. Level 5 is for upper-intermediate to advanced level students. The Teacher's Book offers a guide through the Student's Book material to enable teachers to plan their lessons quickly and effectively. It also gives background information about the topics in the Student's Book, and optional extra lesson ideas. Each level of the course provides 80-90 hours of class work with extra photocopiable activities and tests in the Teacher's Resource Pack. The course can be used with mixed-ability classes.
