Hi，there.
I am planing to take part in toefl test in north america. But now I have no idea about the materials of preparation for the test. Now I am living in CA(加州）。Are there any people who had the experience or who want to have a toefl test?  I appreciate that someone can tell me about the preparation materials of IBT. And we can communicate and share information and encouragement.

Thanks god for giving me you, my friends.
