I've seen some bad reviews for the élan books, but given that our entire college language department uses these books, I can see that it's for a good reason. The book contains all you will possibly need for your learning of the topics throughout your AS/A level course, well, a very good initial structure, with which you can then expand upon, either with teachers notes or your own learning. Each section is broken up with key exercises that not only incorporate the subject at hand, but also work in short, yet effective grammar exercises that gradually get more difficult as your French progresses over the year. What's more, each topic has a review and summary section the end of it, thus allowing you to consolidate all that you have learnt and test your grammar skills again. For me it's a 5 star buy.
