There are many reputable (and some less reputable) study guide books available in multiple languages, aimed at helping students better prepare for their TOEFL test. With so many books to choose from, you want to find the one or two that will really help you achieve TOEFL success.
When you’re choosing a study guide book one of the first things you’ll want to do is be sure to consider the type of TOEFL test you need to prepare for. Not many places still offer the written test, so you’re more likely to write a computer-based test (CBT) or an internet-based test (iBT). Also, look for a current edition.
ETS (Educational Testing Service) is the company that manages and creates the TOEFL tests, and so naturally their study guides are really popular.
Look for guide books that have CD’s to help with listening comprehension and audio exercises. Sample tests should also be included, preferrably with answer keys. I find the student planners included in some books help my students reach their study objectives in an organized manner.
The essay-writing section of the book should be clear and with many examples and opportunities to write your own. Practice drills of all aspects of the TOEFL test are key to success.
If the study guide your considering doesn’t meet the above recommendations, keep looking! And remember, this is a challenging test and there is no “magic book” that will magically prepare you for your TOEFL test. You’ll need to study hard, work with an ESL Teacher or Tutor who specializes in TOEFL test prep and find opportunities to practice the language.
