Before TOEFL I was not sure if a workbook is actually necessary because I quite feel safe in the English language. In retrospect, I am very glad to have had this book in preparation. The time the TOEFL is extremely tight, so it is good if you already know get what types of questions to a what is expected from a how to tackle the question types is best, etc. In addition, quite a lot of value in the correction on well set the structure of the responses, and these can be trained optimally with the book. The book is less likely to improve his English skills but serves purely preparation for the test, which means it is also those who are not so sure in the language explains how they can use their knowledge bring out the most. The book puts great emphasis on the form of responses and how to maximize his chances of a good evaluation even with uncertainties. However, no grammar exercises or something similar in the book available. The meaning of the first part, I did not quite understand, the question types are roughly explained, but it all sounds quite simple. Later in the book, however, by working closely with reference to numerous practice tests (the approach of difficulty ago exactly to the TOEFL) every line of questioning. I have the right TOEFL iBT with 119 able to complete 120 possible points, I think the book would be without the several points have been less. I think it is therefore a very useful preparation for the test.
