Oh!!! I Didn't notice that my Special Program(!!!!!) was Open!!!
I don't know about books that help to get ready for Toefl, and I think it's better to have a teacher for the last 6 month remain to the exam.
I love Extra Series, It's so sweet. and I think watching animations and movies will be very helpful. I have some lovely animations that I can give to you If you are interested. and you know, I think language and speed of talking in classic movies is very good for improving listening.
And in my opinion the Most useful stuff for listening is Audio Books, in audio books official accent speaks very clearly,you can listen to them half an hour in bed or when you do something that don't need concentration.
