Cambridge IELTS 13 Academic Student’s Book with Answers with Audio

The International English Language Testing System (IELTS) is widely recognised as a reliable means of assessing the language ability of candidates who need to study or work where English is the language of communication. These Practice Tests are designed to give future IELTS candidates an idea of whether their English is at the required level. IELTS is owned by three partners: Cambridge English Language Assessment, part of the University of Cambridge; the British Council; IDP Education Pty Limited (through its subsidiary company, IELTS Australia Pty Limited). Further information on IELTS can be found on the IELTS website www.ielts.org.
