i am also taking it soon,i guess there are a few CD s you get on the net and the site of TOEFL(www.toefl.org)........i dont know this will help but this is all i know for now......good luck 🙂
I bought a cd for writing section. It s very useful .I did all the test that I found on net and I studied some English grammar.If you live in an English area ,you will not have any problems with speaking test.
Good look & take care, everybody!
