How can I get a high score in the IELTS?
Well, there is no "one method/one strategy" to get better scores.
Primarily, you have to find out where are you lagging behind? Like, is it the listening section you are getting less scores or reading or speaking or writing?
Listening and reading, you can identify your own mistakes if you are making any. Whereas speaking and writing you would need someone to tell you where are you going wrong?
Listening & reading, the only key to master them is persistent practise. Firstly take a test, check your answers and then question yourself why did you choose wrong one and not the right one. & make sure you don't repeat the same mistake.
Speaking, you can record your voice & listen to it; you will be easily able to find out if you are making any mistakes. Watch couple of videos available on Internet to get to know how exactly the speaking exam is conducted.
Writing, you can write and send it to those netizans who charge some amount for evaluation & give you the feedback.
