TOEFL preparation

I have found a computer software that has 49 practice tests for the TOEFL test takers. I hope that will help you to get the score that you want. In order to use this software you have register to www.zhan.com as overseas user then you will have an able to download to TPO 1-49 software. If you use only a smart phone not a laptop, that's not problem there is still applications for IOS and Android, which is amazing.
