"As a British Council-certified IELTS Trainer, I would advise you join for a class to improve your chances of success. A good trainer can help you out with your Speaking and point out your errors and make suggestions on how to improve in Writing. Plus, he/she might even be able to help you maximise your Reading and Listening skills by offering you tips and shortcuts to get the right answers.
I would also ask you to look at putting in about 4.5 hours into your training daily, and train for about 10-12 weeks before taking the Test. This is what I find from my experience to be the average requirement for getting a 7.0 in all the four modules(Listening, Reading, Writing, Speaking)"
..."All I can tell you is that your scores are going to be directly proportional to the amount of effort you put in. I have yet to come across a candidate who worked hard and failed to get good scores.
