Each Teacher's Book includes a DVD-ROM containing a series of tests (unit, term, final and exam-related), a test generator for bespoke testing and a number of teacher-support videos featuring the Laser authors, Malcolm Mann and Steve Taylore-Knowles. An additional disc provides access to the Digibook, which is a page-faithful version of the Student's Book and is designed for teacher use in the classroom or student homework. sakriti opis
