So many books and softwares you can use for TOEFL. I will suggest you to check this one: Cracking the TOEFL iBT if you wanna take internet based TOEFL. I think this book help me to pass my past TOEFL test. Btw, other materials such as Longman, Kaplan, and Cambridge give other ideas how to deal with TOEFL. Wish this will help you

Thanks a lot Sokhid, I'll give it a try.
