Ready for First The best FCE coursebook is Ready for First by Roy Norris. (It used to be called Ready for FCE but Cambridge changed the name of the exam.) It teaches all the grammar and vocabulary you need, plus the exercises are formatted exactly the same as in the exam.
That means you're getting exam practice while you're learning English. I use this with all my FCE students and I even use it with students who don't want to take the exam, because the reading texts are interesting and there's great variety in the topics. If you can afford it and you have the time to do extra work, buy the workbook as well. (You'll see it listed on Amazon when you follow the link.) Coursebook + Workbook = pass the exam. If you just want to improve your grammar (and don't need the listening exercises) you can get, which is awesome. Listening Practice AUDIOBOOKS I love audiobooks. If you've never tried one, you can use this link to sign up with Audible.com and get two free audiobooks (which you can keep if you don't want to continue using Audible).
