I've purchased the Official Guide to the TOEFL Test in preparation because I necessarily need a TOEFL Rating for a semester abroad. Due to previous internet research my choice then fell on this copy and I was not disappointed. The descriptions in the book are very detailed and there is a very clear exactly what is important. The enclosed CD also contains 3 old tests, which simulate the exam situation under time and difficulty perfectly. With the help of this book I have passed the test without any problems and can now look forward to a semester abroad me :) Therefore, there is of me full 5 stars !!
