Practice is the only way to get scoring in Toefl. whatever u practice, do it within time limit especially while speaking section. Use a timer and a recorder. Listen and pick out ur mistakes. You tube is a good source to practice and learn. Check out this site. it helped me a lot. I did not give my best but was stil able to score 106.
