iPass Ielts was most useful to my Ielts preparation. Firstly, it is not expensive at all. Secondly, you can practice everywhere and anytime you want, you just need to turn your computer on. Thirdly, the listening practice, by skype with Jenny and Nigel, is very helpful too. It will help you to develop your communication skills, discussing a wide range of topics which are frequently needed for your Ielts listening task. Lastly, I got an overall band of 7,5, just what I needed to get into my Master Degree. Thanks a lot, iPass Ielts.
