Starting with the IELTS preparation, give an hour to every module. Practice each and every module in the given time frame. Look out for your mistakes and attempt not to repeat them, even if you have to pay attention to that recording once more or you have to study that passage again.
Just try no longer to repeat them. Always give the test in the specific time limit. Once 60 minutes are over, give up your Reading section and check your answers. After scoring yourself, then clear up the remaining questions. Same goes with the Listening section.
Take a full Speaking examination and record your voice for the first few days. After completing the exam, pay attention to your recording. Judge and score it. You should no longer be repeating words and using fillers like ‘hmmm…’, ‘mmm’ and similar voices. If you think, your voice is not appropriate and clear, examine aloud something in English EVERYDAY for 30 minutes until your day of an exam. This will surely help you.
Coming to Writing, it comes with practice. Learn some words, phrases and idioms daily and attempt to use them in your writing. Read some suitable excellent articles from magazines and newspapers every day. Find someone who will be equipped to rating your writing duties every day.
If after doing the full practice tests for a few days, you feel you are weak in a specific section, double the time for that specific section and strive to improve in that.
