QSE provides a rich resource of 4-skills practice, which can be used alone, or as supplementary material with the Betsis Practice Tests books.
QSE is written by well-established authors and uses the latest ideas about brain science and language acquisition, from multiple intelligences to memetics.
QSE is the first course to offer Content and Language Integrated Learning (CLIL) as a seamless part of every Unit.
QSE is not afraid to tackle topics that the usual EFL materials ignore, dealing with the controversial ideas and issues that students really want to discuss - families, global warming, animal welfare, ambition and careers, love & relationships, fame & fortune, peace & war.
QSE has Units at all levels with a similar, easy-to-follow format, so that teachers and students can quickly and easily tackle new topics, with minimum preparation time.
