Recommended IELTS Books

Cambridge Grammar for IELTS is useful because it has an entry test and candidates getting most of the questions correct are likely to be upper intermediate level (band 7).  The grammar lessons are particulary useful and there are samples of IELTS listening tests as well.  It contains Academic & IELTS reading questions focusing on some of the main skills tested in the exam.

IELTS Practice Tests Plus 2 has 6 full IELTS tests for all the components of the exam.  The teaching at the beginning of the book on what the examiner is looking for in the speaking section is extremely useful.  The writing tutorials for Academic and General writing are also very helpful - particularly Academic Task 1 writing.
