I have a new student from Germany (advanced) who would like me to recommend a series of grammar texts that he can use in order to brush up on his English which in general is very good...if given a list of good ones, he would be quite capable of deciding which series would best suit his learning style.
I'm familiar with the Azar series, Grammar Dimensions, and Headway.
I realize that there must be many new texts on the market since the above were recommended to me quite some time ago. Teachers/moderators...I'd love to get some feedback on your favourites and briefly why you favour them.
If your student is advanced, then she/he would be better off concentrating on acquiring a wider vocabulary and using a course book such as Inside Out Advanced. If he/she really just needs to revise grammar, then perhaps Hewing's Advanced Grammar in Use - this is not a course book just grammar practice with explanations.
