Hi to everybody!
I would like to take a TOEFL test this year and i need to prepare myself about the structure of the test and his "tricks and tips". I'm italian, so i need a book that has to be very helpful in all sections but also grammar and vocabulary.
Reading your topics i think the Official Guide ETS is a must have. So I'm going to buy one. But for grammar and vocabulary do you suggest something in particular?
And, most of all, do you think that for a non-native english the official guide is enough to achieve an excellent score (considering a medium level of english) or i need something else?
