Insight into IELTS
I have never worked my way through this whole book, but every time I have used with an IELTS class I have found something that I can actually use with other classes, such as EAP and Business students, so I now turn to it regularly as a supplement. Generally one of the most popular exam textbooks in out teachers’ room, and there isn’t a lot of competition for a textbook for an IELTS class.
