Again thanks a lot to your help.
My score:
Listening: 27
Structure/writing:28
Reading: 27
Essay rating: 5.5
Total score:273.
I'm very happy :D and I didn't expect the essay score. One advise, if you are not good are writing (that's my case), buy the book How to prepare for the Computer-Based Toefl essay. Probably without the book my essay score would be 3.
Now I have to start studying for the GMAT. Are the essays comparable between GMAT and TOEFL. Can I prepare them in the same way?
Best regards
Lorenzo
PS. Keep working for the site, it's the best I found on Internet (and I've searched a lot!!!)
