I just reviewed myself, I downloaded on my google play all about IELTS and I'm happy because I can practice every day.
No time to go to Review Center because I have a baby. It's so difficult to travel and quite expensive, so learning yourself might help you. I'm focussed right now on listening, because it's quite hard for me. So I keep on practicing every day...speaking quite okay, because they said its more personal based on our experience.
